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 ...
Cavitation damages morphology of high-strength low-alloy steel
(Croatian Metallurgical Soc, Zagreb, 2016)
This paper presents the research into behaviour of HSLA steel affected by cavitation. The parent material (PM) and simulated heat-affected zone (SHAZ) were studied. Ultrasonic vibratory cavitation test was performed in ...
Development of contemporary procedures for lead obtaining / Razvoj savremenih postupaka dobijanja olova
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Contemporary procedures of lead concentrates treatment were in different expansion during last thirty years. All procedures have in common the following: smelting reaction proceeds in solid-gas suspension, melting products ...
Microstructure evolution of the hot-rolled modified AA 5083 alloys during the two stage thermal treatment
(Savez inženjera metalurgije Srbije, Beograd, 2011)
The effects of the two stage heat treatment on the structure of two hot-rolled 5083 aluminum alloys without and with 0.12% Zr addition were investigated. Combination of the metallographic and transmission electron microscopy ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
A two-stage metal valorisation process from electric arc furnace dust (eafd)
(Croatian Metallurgical Soc, Zagreb, 2016)
This paper demonstrates possibility of separate zinc and lead recovery from coal composite pellets, composed of EAFD with other synergetic iron-bearing wastes and by-products (mill scale, pyrite-cinder, magnetite concentrate), ...
The influence of thermomechanical treatment on recrystallization of AlMg4.5Cu0.5 alloy
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behavior of an Al-Mg-Cu alloy (4.5 wt. %Mg and 0.45 wt %Cu) subjected to different thermomechanical treatments (TMTs) have been studied by means of light optical microscopy and hardness measurements. In ...
Dynamic recrystallization in M2 tool steel during friction welding
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Friction welding of M2 tool steel and 1730 quenched and tempered steel was performed with the aim to reveal the origin of extremely fine martensitic grain in M2 steel after welding. Taking into account thermomechanical ...
Tensile properties of fiber-resin composites that consist of polyarmid fiber (Kevlar 129) and poly(vinilbutyral) / Zatezna svojstva polimernog kompozitnog materijala poliaramidna vlakna (Kevlar 129) - poli(vinilbutiral)(PVB)
(Savez inženjera metalurgije Srbije, Beograd, 2006)
Thanks to fact that composite material have usefully characteristic two or more materials, they are becoming more and more substitute standard materials in every field of technique they start to. In this study static ...
Properties of Cu-Al2O3 Powder and Compact Composites of Various Starting Particle Size Obtained by High-Energy Milling
(Savez inženjera metalurgije Srbije, 2009)
Copper-based composites were obtained using high energy milling. The inert gas-atomized prealloyed copper powder (average particle size - 30 μm) containing 2 wt.% Al, and the mixture of electrolytic copper powder (average ...
