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 ...
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 ...
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 ...
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 ...
