AB  - Wrought Al-Mg alloys are important and promising material for application in transportation industry primarily due to favorable strength to weight ratio. As a result of their usage in the field of transportation, the weight of vehicle constructions become reduced, resulting in a decrease of fuel consumption and carbon dioxide emissions. In addition to these advantages, one of the important demands on the application of Al-Mg alloys as a light weight structural material, is providing a high strength, corrosion resistance and good surface quality without relief caused by yield point phenomena and serrated flow. Such a good combination of properties can be achieved by a variation and optimization of thermomechanical processing parameters including a degree of deformation and annealing conditions. 
In this study we investigated the effect of cold rolling reductions and different annealing conditions, on the corrosion resistance and mechanical properties of an AA5182 type Al-Mg alloy. Material was industrially produced and supplied by Impol-Seval Aluminium Rolling Mill, Sevojno, Serbia, as hot rolled 12 mm thick plates. Further lab-processing of hot rolled plates included cold rolling with 40-85% reduction in thickness, and annealing in the range of temperatures 280-350°C, in a different period of time. Annealed specimens were used for room temperature tensile testing while corrosion testing was performed on the annealed and sensitized specimens. Intergranular corrosion (IGC) susceptibility was determined by nitric acid mass loss test (NAMLT) for the selected states. 
The results showed that corrosion resistance, tensile strength and yield point elongation were mostly affected by a degree of cold deformation. It was found that increasing in cold rolling reduction from 40-85% before annealing causes an improved strength level due to grain size refinement. However, yield point elongation became more pronounced and a tendency towards Lüdering as undesirable surface appearance was increased. NAMLT testing showed that the material was corrosion resistant in as-annealed condition while it became susceptible to intergranular corrosion after sensitization treatment. IGC susceptibility of sensitized specimens increases with cold rolling reduction and a raise of annealing temperature.

AB  - The pattern recognition approach, explored by this study, applies the principal component analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation and propagation of the cracks and defects that appear on the surface of material exposed to the cavitation. The experiment was performed in four stages: (a) synthesis of two ceramic materials (cordierite and zircon); (b) subjecting the samples to the cavitation; (c) using image analysis software for collecting the data about morphological characteristics that describe defects; (d) principal component analysis as a pattern recognition tool in order to characterize the defects at the material surface. Besides that, according to standard, cavitation erosion was monitored by determining material mass loss during the cavitation. Large experimental datasets collected from morphological descriptors by image analysis are multivariate and difficult to interpret, thus are processed by principal component analysis as the most informative technique for extracting possible differences. The performed approach proved that this method has a great potential for better assessment of induced defects by proper distinguishing among them at different levels and that can be considered a very efficient and cost-effective one.

Metallic,ceramic, and composite materials are usual candidates considered for application in such extremeconditions. In this study, the idea is to synthesize refractory ceramic material based on talc withthe addition of zeolite for utilization as protective coatings in cavitating conditions. Two talc-basedrefractories with zeolites from two Serbian deposits were produced. The behaviors of the samplesin simulated cavitation conditions were examined by an advanced non-destructive methodologyconsisting of monitoring mass loss and surface degradation using image analysis compiled withprincipal component analysis (PCA), interior degradation by ultrasonic measurements, and themicrostructure by a scanning electron microscope (SEM). Lower mass loss, surface degradation level,and modeled strength decrease indicated better cavitation resistance of the sample with Igros zeolite,whereby measured strength values validated the model. For the chosen critical strength, the criticalcavitation period as well as critical morphological descriptors, Area and Diameter (max and min),were determined. A Young’s elasticity modulus decrease indicated that surface damage influenceprogressed towards interior of the material. It can be concluded that the proposed methodologyapproach is efficient and reliable in predicting the materials’ service life in extreme conditions.

AB  - Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow is present, which contains equipment such as turbine blades, high-speed propellers, or
pump parts. Cavitation erosion usually causes surface degradation of material with defects that appear in
the form of pits and fractures. Such loss of material leads not only to surface degradation but usually also
to strength deterioration with the potential risk of failure and therefore also to shortening of material
lifetime, thus requiring additional costs for failure analysis, repair, and replacement of parts. This paper
will present the results regarding the resistance of various engineering materials to cavitation erosion. As
materials, austenitic stainless steel 316L and CuAlNi shape memory alloy are selected and studied. The
comparison of the behavior between these two materials in cavitation erosion conditions will be shown
based on the results of mass loss and morphology analysis of the pits formed at the surface over time. Image
analysis tools will be applied in order to quantify the surface damage level and to analyze selected
morphology descriptors.

AB  - The paper presents the results of the research cavitation erosion behavior of samples based on talc with addition of domestic zeolite from the Zlatokop deposit. Samples based on talc with 15 % of zeolite, from Zlatokop (Vranjska Banja), sintered at 1200ºC were used in this investigation. Resistance to cavitation was monitored by the ultrasonic vibratory cavitation set up with a stationary specimen and measuring respectively determining the specimens' mass loss. Image analysis and Young's modulus of elasticity were used to determine the level of degradation of the sample surface and sample’s volume. Obtained results showed good resistance of the refractory samples based on talc and zeolite to the cavitation erosion, which indicates the possibility of application ceramic samples based on talc and zeolite in various areas of industry where the presence of destruction due to the effect of cavitation is expected.

AB  - To evaluate the effect of homogenization conditions on the possible loss of low-melting-point Pb and Bi to the surface in the free-cutting AA6026 alloy, three homogenization regimes were applied: 480 degrees C/12 h, 530 degrees C/12 h, and 550 degrees C/6 h. The microstructural characterization by optical, scanning, and transmission electron microscopy coupled with EDS analysis, macroanalysis of chemical composition by ICP-AES as well tensile tests at room and 500 degrees C, and Charpy impact test were employed to evaluate the different homogenization regimes. It was found that the choice of homogenization temperature had no significant effect on the level of loss of low-melting point elements. The optimal homogenization regime appeared to be 550 degrees C/ 6 h as it led to almost complete beta-AlFeSi -> alpha-AlFe(Mn)Si transformation and beta-Mg2Si dissolution resulting in improved mechanical properties. The presence of the liquid phase did not lead to catastrophic failure due to the liquid metal embrittlement of the aluminum matrix, but the wetting of Fe,Mn - bearing constituents by molten Pb led to decohesion of the constituents. The morphological change to globular alpha-AlFe(Mn)Si decreased the surface area and interconnectivity of the microconstituents, which improved the hot ductility. During cooling after homogenization at T > 500 degrees C, the Q-phase precipitated, pointing up the potential quench sensitivity of the alloy. However, precipitation of the Q-phase laths in dispersoid-free zones reduced strain localization and improved room temperature ductility and impact toughness.

AB  - Ternary Cu-2.71Zr-2.27B (wt.%) alloys were fabricated using powder metallurgy, i.e., 
mechanical alloying followed by cold pressing and sintering. Influence of the mechanical 
alloying parameters on microstructural and morphological changes of Cu-Zr-B powder mixture 
was investigated using scanning electron microscopy and X-ray diffraction. Stereological 
analysis was employed to determine changes in size and shape of copper particles during 40 
hours of mechanical alloying. It was shown that with an increase in mechanical alloying time, 
the size of copper powder decreases. Williamson-Hall analysis was used to calculate crystallite 
sizes (D, nm), lattice parameter (nm), lattice strain (ε, %), and dislocation density (ρ, m-2). It was 
shown that with increasing mechanical allo ying time, lattice parameter as well as lattice strain 
both increases. Particles undergo high forces through ball-particle-ball and wall-particle-ball 
collisions during mechanical alloying. These collisions induce accumulation of dislocations in 
copper matrix and a decreasing in its crystallite size due to dominant plastic deformation 
mechanisms. Dislocation densities reach its maximum value at around 30 hours of mechanical 
alloying, after which they decrease owing to the recrystallization of copper matrix.

AB  - Purpose: Immature teeth are characterized by short roots, thin root canal walls, and open apices, which makes them prone to fracture. The aim was to investigate whether fiber-post placement had an influence on the fracture resistance of endodontically treated immature teeth. Materials and Methods: To simulate immature teeth, the apical third of 20 intact mandibular premolars was resected. After the access cavity was prepared, root canals and apices were enlarged. A 4-mm apical barrier was placed using calcium-silicate based material (Biodentine, Septodont). The teeth were then randomly assigned to two groups (n = 10). Root canals in group 1 were sealed using Acroseal (Septodont, France) and gutta-percha, followed by composite resin for the coronal restoration (Evetric, Ivoclar Vivadent). In group 2, fiber posts (FRC Postec Plus, Ivoclar Vivadent) were luted using self-adhesive composite cement (SpeedCEM Plus, Ivoclar Vivadent), followed by the same coronal restoration. The teeth were then subjected to fatigue and static load testing. Results: The average loads (+/- SD) that led to tooth fracture were: 401.40 +/- 296.83 N in group 1 and 636.20 +/- 204.95 N in group 2. Unfavorable fractures were noted in 9 specimens from group 1 and in 7 specimens in group 2. No statistically significant difference in fracture resistance or fracture mode was found between the groups. Conclusion: Fiber-post placement had no significant influence on the fracture resistance of endodontically treated immature teeth.

AB  - High-temperature materials are used in a wide range of industries and applications such as gas turbine engines for aircrafts, power and nuclear power plants, different types of furnaces, including blast furnaces, some fuel cells, industrial gas turbines, different types of reactors, engines, electronic and lighting devices, and many others. Demands for high-temperature materials are becoming more and more challenging every year. To perform efficiently, effectively and at the same time to be economically viable, the materials used at high temperatures must have certain characteristics that are particularly expected for applying under such extreme conditions, for example, the strength and thermal resistance. In the present review, some important requirements that should be satisfied by high temperature materials will be discussed. Furthermore, the focus is put on refractory concretes, ceramics, intermetallic alloys, and composites as four different categories of these materials, which are also considered in respect to possibilities to overcome some of the current challenges.

AB  - The occurrence of abnormal grain growth (AGG) in AA5182 alloy during annealing imposes severe restrictions on processing parameters and deteriorates mechanical properties. In this work, we investigated the effect of chemical composition on the appearance of abnormal grain growth by varying Mg and Mn content in the range of composition limits for standard AA5182 alloy, 4.0-5.0% Mg, and 0.2-0.5% Mn, respectively. Thermo-mechanical processing of alloys included cold rolling with reductions ranging from 40 to 85%, followed by annealing in the temperature range from 350 to 520 degrees C. The results showed that the rise in alloying elements content drives the onset of abnormal grain growth toward higher temperatures. The increase in the cold rolling reduction degree promotes abnormal grain growth and lowers its onset temperature. Abnormal grain growth and grain boundary mobility showed strong anisotropy related to rod-like shape and alignment of Al6Mn(Fe) dispersoids through Zener pinning.

AB  - Ispitivan je uticaj stepena i načina deformacije na korozionu stabilnost legure AA5083 koja
je procesirana konvencionalnim valjanjem (CR) i akumulativnim spajanjem valjanjem (ARB).
Koroziona stabilnost je praćena standardnim elektrohemijskim metodama,
spektroskopijom elektrohemijske impedancije (EIS) i polarizacionim merenjima. Utvrđeno
je da je gustina struje korozije (jcorr) manja za najmanje jedan red veličine kod ARB višeslojnih
uzoraka. Veći stepen deformacije indukovao je bolju korozionu stabilnost CR jednoslojnih,
kao i ARB višeslojnih uzoraka. Rezultati pokazuju da je ukupna impedancija ARB višeslojnih
uzoraka više nego udvostručena u odnosu na CR jednoslojne uzorke kao rezultat višeslojne
strukture i prisustva oksidacionog filma između slojeva. Značajno veći polukrugovi na
Nyquist-ovim dijagramima za ARB uzorke ukazuju na povećanu korozionu stabilnost, koja
raste sa porastom stepena deformacije. Eksperimentalni rezultati pokazuju da način i
stepen deformacije imaju veliki uticaj na korozionu stabilnost AA5083 legure.
AB  - The influence of the degree of deformation and applied processing route on the corrosion
stability of AA5083 alloy sheets processed by conventional rolling (CR) and accumulative roll
bonding (ARB) has been studied. The corrosion stability was evaluated by standard
electrochemical methods, electrochemical impedance spectroscopy (EIS) and
potentiodynamic measurements. It was found that the corrosion current density (jcorr) is
smaller for at least one order of magnitude for ARB multilayer samples. Higher degree of
plastic deformation induced better corrosion stability, for both CR monolayer and ARB
multilayer samples. Results showed that the overall impedance value of ARB samples was
more than doubled compared to the CR samples as a result of the multilayered structure
and the presence of oxidation film between the layers. Significantly larger semicircles in
Nyquist plots for ARB samples indicate increase of corrosion stability, with increasing the
number of ARB cycles. Experimental results showed that applied processing route and the
degree of deformation have a major impact on the corrosion stability of the AA5083 alloy.

AB  - Influence of accumulative roll bonding (ARB) and conventional cold rolling (CR) on the mechanical and corrosion properties of AA5083 alloy sheets has been studied. Tensile tests showed significant increase in strength and a decrease in elongation after each ARB deformation and cold rolling reductions. Results of nitric acid mass loss test (NAMLT) revealed that cold rolled and ARB processed specimens were resistant toward intergranular corrosion (IGC) in as-deformed state. However, after 7 days of sensitization at 100 and 150 degrees C, cold rolled material became IGC sensitive, while ARB specimens stayed IGC resistant. IGC susceptibility can be correlated with different morphology and distribution of -phase (Mg2Al3) precipitated during sensitization. It was found that extensive shear banding contributed a favorable distribution of -phase precipitates in the structure of IGC resistant ARB processed specimens. In case of IGC susceptible conventionally cold rolled specimens, large amount of -phase precipitated preferentially along the elongated grain boundaries. Electrochemical parameters were in a good correlation with the results of NAML tests, which in turn, confirmed the superiority of ARB multilayered structure over conventional cold rolled structure in terms of IGC susceptibility and corrosion stability.

AB  - Influence of accumulative roll bonding (ARB) and conventional cold rolling (CR) on the mechanical and corrosion properties of an AA5083 type alloy with 4.2 wt% Mg and a modified alloy with 5.1 wt% Mg and addition of 0.5 wt% Zn was studied. Tensile tests showed significant increase in strength and a decrease in elongation after each ARB deformation and cold rolling reductions. The advantage of ARB processing over conventional cold rolling was due to the possibility to achieve high degree of deformation and a grain structure refinement. Higher Mg content in a modified AA5083 alloy contributed significantly to the increase in strength, while strain hardening potential and corrosion resistance were reduced. The higher strength level of cold rolled material was attributed to higher dislocation density and the hardening effect due to more intensive dislocation interactions compared to ARB processed material. Results of nitric acid mass loss test (NAMLT) revealed that cold rolled (CR) monometal and ARB processed multilayered specimens were resistant toward intergranular corrosion (IGC) in as-deformed state. However, after 7 days of sensitization at 100 and 150 °C, CR material of AA5083 alloy became IGC sensitive, while ARB specimens stayed resistant. On the other hand, both cold rolled and ARB processed specimens of a modified alloy became IGC susceptible after sensitization. IGC susceptibility of the tested alloys can be correlated with different morphology and distribution of β-phase (Mg2Al3) precipitated during sensitization. It was found that an extensive shear banding within ARB multilayered structure and the existence of passive film between the layers contributed a favorable distribution of β-phase in the structure of IGC resistant ARB specimens. In case of IGC susceptible cold rolled specimens, large amount of β-phase precipitated preferentially along the elongated grain boundaries. Electrochemical parameters were in a good correlation with the results of NAML tests, which in turn, confirmed the superiority of ARB multilayered structure over conventional cold rolled structure in terms of IGC susceptibility and corrosion stability.

Rezultati ispitivanja jednoosnim zatezanjem pokazali su da dolazi do značajnog povećanja parametara čvrstoće i smanjenja izduženja nakon svakog ARB provlaka i sa porastom stepena deformacije CR postupkom. Pokazana je prednost ARB postupka nad klasičnim postupkom hladnog valjanja obzirom da se mogu postići veći stepeni deformacije i veća rafinacija strukture. Pokazano je da povišen sadržaj Mg doprinosi porastu čvrstoće, dok se potencijal za ojačavanje i koroziona otpornost smanjuju. Viši nivo čvrstoće CR traka rezultat je veće gustine dislokacija i izraženijeg deformacionog ojačavanja zbog intenzivnije interakcije dislokacija kod konvencionalnog valjanja u odnosu na ARB postupak. Rezultati testa gubitka mase (NAMLT) pokazali su otpornost jednoslojnih CR i višeslojnih ARB traka ispitivanih legura prema intergranularnoj koroziji (IGC) u deformisanom stanju. Međutim, nakon 7 dana senzitizacije na 100 i 150 °C, CR uzorci AA5083 legure postaju osetljivi, dok ARB uzorci ostaju otporni prema IGC. Za razliku od standardne legure, CR i ARB trake modifikovane legure pokazale su veliku osetljivost prema IGC nakon tretmana senzitizacije. Osetljivost prema IGC u korelaciji je sa različitom morfologijom i raspodelom β-faze (Mg2Al3) istaložene tokom senzitizacije. Otkriveno je da postojanje smicajnih traka usled intenzivne plastične deformacije u višeslojnoj ARB strukturi, i pasivnog filma između slojeva doprinosi povoljnoj raspodeli β-faze u strukturi otpornih ARB uzoraka što su potvrdili i rezultati elektrohemijskih ispitivanja. U slučaju IGC osetljivih CR uzoraka, velika količina β-faze istaložena je duž granica zrna. Elektrohemijski parametri su u dobroj korelaciji sa rezultatima NAML testa, koji su potvrdili prednost ARB višeslojne strukture u odnosu na konvencionalno hladno valjanu, i ustanovljeno je da ARB postupak ima realnu mogućnost praktične industrijske primene za izradu višeslojnih traka jer omogućava transformaciju Al-Mg legura u materijale novih, pobolјšanih svojstava.

Elektrohemijski parametri su u dobroj korelaciji sa rezultatima NAML testa, koji su potvrdili prednost ARB višeslojne strukture u odnosu na konvencionalno hladno valjanu, i ustanovljeno je da ARB postupak ima realnu mogućnost praktične industrijske primene za izradu višeslojnih traka jer omogućava transformaciju Al-Mg legura u materijale novih, pobolјšanih svojstava.",

AB  - The aim of this paper was to determine the causes of screws failures in compressor valves, obtained from petroleum industry. The analysed screws were in exploitation and deposition coated. Before the fracture analysis, control calculation of screws is done in order to determine, if the screws are properly dimensioned. After visual and radiographic examination, their chemical composition and structure were analysed. Detail fractography was performed on fractured surfaces to try to obtain an impression about screws failure mechanism. Qualitative analysis of deposit was employed in order to confirm if there was any possible influence of surroundings during their failure in terms of corrosion-assisted cracking. The macrofractography of originally broken surfaces shows a rough and complex topography of fracture surfaces indicating to a possibility that screws failure has been a result of complex loading conditions. Presence of sulfur containing particles on the fracture surfaces of broken screws and in deposit reveals a possibility that failure was environmentally-assisted.

AB  - Poslednjih godina sve više pažnje se posvećuje spajanju legura aluminijuma i drugih metalnih
materijala lepljenjem pomoću odgovarajućih adheziva. Time se obezbeđuje spajanje metala u
slučajevima kada uobičajeni postupci zavarivanja nisu mogući. Na tržištu postoji veliki broj
različitih adheziva za čiju izradu se koriste komponente dobijene iz petrohemijskih izvora koje su
štetne po zdravlje ljudi i životnu sredinu. Zbog toga je trend u industriji adheziva da se ove
komponente delimično ili u potpunosti zamene netoksičnim materijalima dobijenim iz obnovljivih
izvora, a da se pri tome zadrži efikasnost adheziva.
U radu je ispitana mogućnost izrade adheziva za spajanje metala u kome je komercijalna epoksidna
smola potpuno ili delimično zamenjena sa prirodnim polimerima, hitozanom i/ili natrijumalginatom. Oko 40 mas.% epoksidne smole je uspešno zamenjeno prirodnim polimerima pri čemu
postignuta jačina adhezije odgovara željenoj vrednosti (4-5 MPa), a u pojedinim slučajevima je i
veća u odnosu na komercijalnu epoksidnu smolu. Optimalni uslovi za postizanje ove vrednosti su
70 C i 24 h. Uočeno je da je tretman površine neposredno pre lepljenja veoma bitan i da ima veliki
uticaj na efikasnost lepljenja, kao i da prisustvo vode smanjuje jačinu adhezije. Pomoću adheziva

AB  - The influence of alloying on the mechanical properties of AA5083 type Al-Mg
alloy sheets produced by accumulative roll bonding (ARB) process was studied.
Two investigated Al-Mg alloys: commercial AA5083 alloy with 4.2% Mg, and modified AA5083 alloy with 5.1% Mg and addition of 0.5% Zn, were supplied by ImpolSeval Aluminium Mill (Sevojno, Serbia) as hot rolled thick plates. Hot rolled plates
were further laboratory cold rolled up to 1 mm in thickness, and ARB processed at
room temperature with ~ 50% reduction per each ARB cycle. It was possible to
conduct up to maximum 6 ARB cycles for a commercial AA5083 alloy and 4 ARB
cycles for modified AA5083 alloy.
Hardness and tensile properties of ARB processed multilayered sheets were
significantly improved with Mg and Zn addition. In the initial annealed state, before
ARB processing, yield strength of the modified AA5083 alloy was only 15-20 MPa
higher than for a commercial AA5083 alloy. However, flow stress level and tensile
strength became higher for nearly 100 MPa after each ARB cycle for the modified
AA5083 alloy in comparison with standard AA5083 alloy. The elongation decrease
value was high after the first ARB cycle, while after subsequent passes it stayed
almost constant, and slightly improved with Mg and Zn addition. Resistivity level
was also affected by chemical composition of the tested alloys. Higher resistivity
level obtained for the modified AA5083 alloy was attributed to higher Mg content
and addition of Zn.
Despite the fact that addition of Mg and Zn limited the possibility of joining
through ARB processing, mechanical properties of the modified AA5083 alloy were
superior over a commercial AA5083 alloy.

AB  - Aluminium alloys with magnesium as the major alloying element constitute a group of non-heat treatable alloys with medium strength, high ductility, excellent corrosion resistance and weldability. Al—Mg alloys are used as structural materials in marine, automotive, aircraft and cryogenic applications.
The chemical composition of tested alloy is. 3.98%Mg, 0.08 %Si, 0.27 %Fe, 0.27 %Cu, 0.7 %Mn, 0.07 %Cr, 1.59 %Zn, 0.017 %Ti and 0.18 %Zr. The structure of Al-Mg-Mn alloy with Zn addition consists of grains of a - solid solution of aluminum with a dendritic-cell substructure, and a variety of intermetallic phases. The distribution of the various alloying elements on the microstructural scale is very inhomogeneous in the alloy. Enrichment of Mg and Zn, depletion of Mn and pre- cipitates of different intermetallic compounds have been observed at the interden- dritic regions of this alloy.
The dominant intermetallic phases formed during solidification of tested alloy have been identified to be AI-Fe-Mn, Al-Zn-Mg and AI-Zn-Mg-Cu. SEM/EDS analy- sis revealed that the MgtSi and Ę phases do not form during nonequilibrium solidi- fication in this alloy.
The zinc addition in tested Al-Mg-Mn alloy precludes the formation of Ę- phase precipitates, resulting instead in the formation of a chemically and structural- ty distinct Al-Mg-Zn phase at grain boundaries and interdendritic regions.
While the I -phase has been reported in 7000 series alloys containing high levels of Zn, this study indicates that the T -phase can also form extensively in AI- Mg-Mn alloy with Zn addition.

AB  - In general, continuous drive friction welding (CDFW) of two metals 
may produce three typical regions from a weld interface towards an unaf-
fected base metal: (i) fully deformed or dynamically recrystallized (DRX) 
region, (ii) partially deformed region or thermo-mechanically affected 
zone (TMAZ), and (iii) undeformed region or heat affected zone (HAZ). 
In past studies, it has been shown that different CDFW parameters may 
differently affect the size and structural properties of these regions. Re-
garding the Al/Cu bimetal joints, past studies have also indicated that the 
self- and inter-diffusion of Al and Cu along the short-circuits (dislocations 
and/or grain boundaries) is the mechanism which probably controls the 
growth of detrimental AlxCuy intermetallics at the Al/Cu interface when 
the temperatures are lower than 350°C. Considering the previous and that 
the permissible operating temperature in Al/Cu and other electrical con-
nections is generally between 100 and 150°C, as well as that the structural 
changes in DRX, TMAZ, and HAZ regions are expected to be slower at 
these operating conditions, it is reasonable to assume that the growth kinet-
ics of AlxCuy intermetallics under these conditions might be different in 
the cases of Al/Cu joints produced with different CDFW parameters and/or 
in the cases of post-weld heat treated Al/Cu joints. The aim of the present 
study was to evaluate the effects of different CDFW parameters and post-
weld heat treatment on the formation of AlxCuy intermetallics on the Al/Cu 

 

interfaces of produced joints when they were submitted to long-term and 
low temperature annealing (similar to mentioned operating conditions). 
Structural properties were analyzed be using the light microscopy and 
scanning electron microscopy.

AB  - Intergranular corrosion (IGC) susceptibility of an AA5083 Al-Mg alloy sheets,
highly deformed by accumulative roll-bonding (ARB), was investigated. It was
shown that ARB processed specimens were resistant to IGC as the mass loss was
<15 mg/cm2. The degree of plastic strain during ARB processing did not affect IGC
susceptibility and a value of corrosion potential. After sensitization treatment at
150°C, ARB processed specimens stayed resistant to IGC, in spite of β-phase
precipitation along grain boundaries and within the structure. A high degree of
deformation achieved by ARB processing, and a large amount of β-phase
precipitated during the sensitization, did not cause an increase in IGC susceptibility
due to favorable morphology and a distribution of β-phase in the structure.

AB  - The effect of different thermo-mechanical processing parameters on the baking response, and intergranular corrosion (IGC) resistance of an Al-4.6 wt% Mg-0.54 wt% Cu alloy was investigated. It has been shown that the high temperature anneal at 530 degrees C resulted in superior baking response of pre-deformed material after short annealing at 140-180 degrees C, compared to the annealing at 280 degrees C. Specimens predeformed 2% had positive baking response for both initial annealing temperatures, however, pre-deformation of 5% induced softening during the baking treatment of the specimens annealed at 280 degrees C. Prior to sensitization of 7 days at 100 degrees C, specimens at all stages of thermo-mechanical treatment were IGC resistant. After the sensitization specimens that underwent annealing at 530 degrees C remained IGC resistant, but specimens that underwent annealing at 280 degrees C became IGC susceptible. Better corrosion properties and baking response are related to the higher Cu content in solid solution after annealing at 530 degrees C than at 280 degrees C.

AB  - The effect of one-step and a new (short) two-step aging process on the resistance to stress corrosion cracking of an aluminum alloy 7000 series was investigated, using slow strain rate test and fracture mechanics method. The aging level in the tested alloy was evaluated by means of scanning electron microscopy and measurements of electrical resistivity. It was shown that the alloy after the new two-step aging is significantly more resistant to stress corrosion cracking. Values of tensile properties and fracture toughness are similar for both thermal states. Processes that take place at the crack tip have been considered. The effect of the testing solution temperature on the crack growth rate on the plateau was determined. Two values of the apparent activation energy were obtained. These values correspond to different processes that control crack growth rate on the plateau at higher and lower temperatures.

Stepen starenja ispitivane legure je procenjen primenom skening elektronske mikroskopije i na osnovu merenja električne otpornosti. Pokazano je da je legura posle novog dvostepenog termičkog starenja znatno otpornija prema naponskoj koroziji. Vrednosti zateznih karakteristika i žilavosti loma su slične za oba termička stanja legure. Razmatrani su procesi koji se odvijaju na vrhu naponsko-korozione prsline. Određen je uticaj temperature rastvora za ispitivanje na brzinu rasta prsline na platou. Određene su dve vrednosti prividne energije aktivacije. Ove vrednosti odgovaraju različitim procesima koji kontrolišu brzinu rasta prsline na platou, na visokim i niskim temperaturama.
