Effect of process parameters on the phase transformation kinetics in copper-based alloys and composites
(Metallurgical & Materials Engineering, 2020)
Copper-based alloys and composites, owing to their convenient properties, are being considered essential materials in various industries. Since copper possesses an ability to develop high corrosion resistance, putting it ...
Influence of the fabrication process of copper matrix composites on cavitation erosion resistance
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Copper matrix composites reinforced with ZrB2 particles were produced in two ways: by hot pressing (HP) and laser-sintering process. Powder mixture Cu-Zr-B was mechanically alloyed before densification processes. Variations ...
Laboratory testing results of kinetics and processing technology of the polymetallic sulphide concentrate Blagojev Kamen - Serbia
(Association of Metallurgical Engineers of Serbia, 2016)
This work presents the laboratory testing results of kinetics the oxidation process and sample processing of the sulphide polymetallic concentrate Blagojev Kamen. The aim of investigation is recovery of these types of raw ...
Kinetics of barite reduction from refractory barite-sulphide ore
(Savez inženjera metalurgije Srbije, Beograd, 2016)
Refractory sulphide-barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships ...
Treatment of dispersed iron-bearing raw materials and modeling of the protection systems against air-pollution
(Association of Metallurgical Engineers of Serbia, 2016)
Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
The influence of Mg and Mn content on abnormal grain growth in AA5182 type alloys
(Savez inženjera metalurgije Srbije, Beograd, 2019)
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 ...
Defect formation during synthesis and welding of silver nanowires for solar cell applications
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Structural defects such as stacking faults and twins, observed in many face-centered cubic (FCC) structured metals and alloys with low stacking fault energies, in general, play an important role in microstructure evolution, ...
The effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
The effect of calcinated hydroxyapatite and magnesium doped hydroxyapatite as fillers on the mechanical properties of a model bisgma/tegdma dental composite initially and after aging
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This study aimed to investigate the possibility of modifying model BisGMA/TEGDMA dental composite by substituting 10 wt. % of conventional glass fillers with bioactive fillers based on calcinated nanosized hydroxyapatite ...
