Influence of vanadium content and colling rate on the stereological parameters of phases in the structure of Fe-C-Cr-V alloys / Uticaj sadržaja vanadijuma i brzine hlađenja na stereološke parametre faza u strukturi Fe-C-Cr-V legura
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper, the influence of vanadium content and cooling rate on the stereological parameters of phases present in the structure of Fe-C-Cr-V alloys. Experimental results indicate that both vanadium content and cooling ...
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 ...
