Influence of chalcopyrite structure on their leaching by sodium nitrate in sulphuric acid
(Savez inženjera metalurgije Srbije, Beograd, 2014)
During the chalcopyrite leaching by sodium nitrate and sulfuric acid solution, leaching rate decreases with increasing the time and a part of chalcopyrite mineral grains remains in the leach residue. In chalcopyrite ...
Semi-empirical software for the aluminothermic and carbothermic reactions
(Savez inženjera metalurgije Srbije, Beograd, 2014)
Understanding the reaction thermochemistry as well as formatting the empirical data about element distribution in gas-metal-slag phases is essential for creating a good model for aluminothermic and carbothermic reaction. ...
The use of electromagnetic field in designing the high qualityal-alloys for hot forging process
(Savez inženjera metalurgije Srbije, Beograd, 2014)
This work presents a way to obtain the better quality of EN AW 7075 aluminum high-strength alloy by application of electromagnetic field (EMF) during the casting process. In this way, the uniform fine-grained microstructure, ...
