The effect of mould temperature and cooling conditions on the size of secondary dendrite arm spacing in Al-7Si-3Cu alloy
(Savez inženjera metalurgije Srbije, Beograd, 2009)
The secondary dendrite arm spacing (SDAS) is one of the most important microstructure features of as-cast structure in hypoeutectic aluminum alloys. The size of SDAS depends on many factors such as liquid metal treatment, ...
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 ...
Hydrometallurgical process for extraction of metals from electronic waste, Part I: Material characterization and process option selection
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling ...
Influence of Cu and Mn content on the properties of Al-Mg4.5-(Mn,Cu) type alloy sheets
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Influence of Cu and Mn content on the grain structure, precipitation effects and mechanical properties of two Al-Mg4.5-(Mn,Cu) type sheets was considered. It was found that a variety of grain size can be obtained in alloy ...
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 ...
Effect of heating rate on precipitation of peak-aged Al-Li (8091) alloy: A quantitative approach
(Savez inženjera metalurgije Srbije, Beograd, 2010)
Samples of Al-Li (8091) alloy were solution treated at 540ºC for 30 min, water-quenched and continuously heated in oil at 0.05 and 0.1ºC/min rates, from room temperature to 190ºC when the peak hardness was achieved. Having ...
Structural properties of Co, Ni and Mo powders obtained by electrochemical deposition
(Savez inženjera metalurgije Srbije, Beograd, 2011)
Magnetic thin films based on iron group elements (Fe, Co, Ni) are currently used in computer's hard disk drives and in MEMS, whereas electrodeposition is a suitable method to obtain these materials. The powders of metals ...
The analysis of the tribological properties of multiple strengthened nanocomposite of the Cu-Al2o3 system
(Savez inženjera metalurgije Srbije, Beograd, 2011)
This paper presents the results of examined tribological properties of the multiple strengthened nanocomposite Cu-Al2O3 system. Cu-Al2O3 composite powder was obtained by combination of the thermo-chemical procedure and ...
Influence of Cr, Mn and Mo on structure and properties of V microalloyed medium carbon forging steels
(Savez inženjera metalurgije Srbije, Beograd, 2010)
The influence of Cr, Mo and Mn on microstructure and mechanical properties of V-microalloyed medium-carbon steels has been studied by means of metallography and mechanical testing. Cr, Mn and Mo addition promotes the ...
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 ...
