Identification of low cycle fatigue parameters of high strength low-alloy (hsla) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Suitability of heat treatment for crack resistance of material in the connection part of heavy transporter for liquid slag
(Croatian Metallurgical Soc, Zagreb, 2014)
The post weld heat treatment (PWHT) was used to reduce the level of the residual stresses and increase of the crack resistance of the material in the connection part.The article presents the results of the residual stress ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
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 ...
