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 ...
Microstructural investigation of the heat-affected zone of simulated welded joint of p91 steel
(Croatian Metallurgical Society, 2013)
In the process of testing teal components exposed to elevated temperature, it is hot possible to neglect Cracks. The most significant cracks can be induced by welding, which is applied for joining of Structural components. ...
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 ...
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 ...
Deformation behavior of the AlMg4.5Cu0.5 type alloy sheet
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Deformation behavior of the AlMg4.5Cu0.5 type alloy sheets was examined after cold rolling and annealing in the range of temperature from 220°C to 520°C, water quenching and natural aging. The low temperature annealed ...
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 ...
A model for predicting fracture toughness in overaged 7000 alloy forgings
(Savez inženjera metalurgije Srbije, Beograd, 2007)
An attempt to develop a multiple micromechanism-based model for predicting plane-strain fracture toughness, KIc, of overaged 7000 alloy forgings has been made. The proposed model reveals the quantitative relations between ...
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), ...
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 ...
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 ...
