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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
Hydrometallurgical process for extraction of metals from electronic waste, part II: Development of the processes for the recovery of copper from printed circuit boards (PCB)
(Savez inženjera metalurgije Srbije, Beograd, 2011)
Rapid technological development induces increase of generation of used electric and electronic equipment waste, causing a serious threat to the environment. Waste printed circuit boards (WPCBs), as the main component of ...
Possibility of secondary lead slag stabilization in concrete with presence of selected additives
(Savez inženjera metalurgije Srbije, Beograd, 2010)
A comparative technical and environmental evaluation of products arising from the stabilization/solidification of secondary lead metallurgical slag into a cement matrix was performed. Provided samples of an industrial slag ...
