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 ...
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 ...
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 ...
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), ...
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 ...
Synthesis and sintering of Cu-Al2O3 nanocomposite powders produced by a thermochemical route
(Savez inženjera metalurgije Srbije, Beograd, 2007)
By hydrometallurgy and powder metallurgy along with prognosis of physical-chemical properties, a synthesis of new improved materials can be successfully performed with in advance pre-set properties which is conditioned by ...
The recycling of high magnesium aluminum alloys estimation of the most reliable procedure
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Aluminum is one of the most recyclable materials. Namely, the properties of aluminum are not affected by the recycling and reuse, thus enable that high value of the metal is maintained after reprocessing. The re-smelting ...
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 ...
