Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
Monitoring the damage level during thermal stability testing of refractory sample using soninic measurement
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Thermal stability of the refractory material with the content of 28 % AI2O3 was investigated. Water quench test (JUS.B.D8.319.) was applied as experimental method for thermal stability testing. Dynamic Young modulus of ...
Studies of a wear resistant cast iron / Izučavanje belih gvožđa otpornih na habanje
(Savez inženjera metalurgije Srbije, Beograd, 2003)
The objective of this investigation was to set down (on the base of the results obtained by the examination of white cast iron alloys with different content of the alloying elements) a correlation between chemical composition ...
Rotating disk alumina precursor fiber formation process stability determination using image analysis
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Precursor fibers are made from the aluminium-hydroxide chloride based sols. The process stability can be influenced both by the fiber formation conditions and the rheology of the sol. The distance from the disk canter is ...
An improved method for thermal stability behavior characterization of silicon carbide/cordierite composite material
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950°C, ...
The effect of mould temperature and cooling conditions on the size of secondary dendrite arm spacing in Al-7Si-3Cu alloy
(Savez inženjera metalurgije Srbije, Beograd, 2009)
The secondary dendrite arm spacing (SDAS) is one of the most important microstructure features of as-cast structure in hypoeutectic aluminum alloys. The size of SDAS depends on many factors such as liquid metal treatment, ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Two microalloyed steels (Nb low carbon and V medium carbon) were tested by means of multistage continuous cooling torsion with aim to evaluate the interpass recrystallization data, by means of Tnr (temperature of ...
Structural characteristics of some ternary Ag-In-Sn alloys
(Savez inženjera metalurgije Srbije, Beograd, 2008)
The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and micro ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
The effect of heat treatment on toughness and wear resistance of Fe-Cr-C-Nb alloys / Uticaj termičke obrade na žilavost i otpornost na habanje Fe-Cr-C-Nb legura
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Alloying with niobium improves the mechanical properties of the high chromium irons. The alloy containing appriximately 3 %Nb gives the best compromise between wear resistance and toughness. These properties were improved ...
