Development of a collision energy absorber of a passenger train
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Development of shock absorbers is one of the necessary measures for passive protection of passenger coaches. The purpose of passive protection is to minimize the collision consequences for passengers. Present solutions are ...
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 ...
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 ...
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 ...
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 ...
Influence of milling parameters on the preparation of fine tungsten and copper powders by mechanically induced self-propagating reaction / Uticaj parametara mlevenja na dobijanje finih prahova volframa i bakra mehanički iniciranom samorasprostirućom reakcijom
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Mechanically induced self-propagating reaction in planetary ball mill was realized in three different systems, CaWO4 (scheelite) + Mg, CuO + Ti and CuO + Zr. An influence of a ball diameter (from 5 to 41.2 mm) at three ...
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 ...
Fuel consumption analysis in cooper melting and refining plants / Analiza potrošnje energenata u pogonima za topljenje i rafinaciju bakra
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Cathode cooper production and refining include significant consumption of almost all-conventional fuel types. The given consumption is high in specific and in nominal way. Especially high fuel value content is on Cathode ...
Optimisation of ferriferous dust and mud preparation acts from iron and steel production on purpose of returning to primary processes / Optimizacija postupaka pripreme železonosnih prašina i muljeva iz proizvodnje gvožđa i čelika u cilju vraćanja u primarne procese
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper detailed characterization of ferriferous dust and mud which originated from aglomerization, blast- furnace and converter process in Iron-works Smederevo were shown. Optimization of method peletization was ...
Experimental and numerical evaluation of a steamline behaviour using local approach
(Croatian Metallurgical Society, 2007)
Results of the experimental and numerical comparative analysis of steamline pipes have been presented. New pipes and the pipes used for more than 117,000 hours at 540 degrees C under pressure of 42 bars have been simultaneously ...
