E-materials become e-waste once they have been discarded without the intent of reuse. Due to its rich content metals, among which many are Critical Raw Materials (CRMs), can be considered an urban mine exploit and valorise. Common metal refining is performed by energy-intensive processes frequently based on use fossil fuel. Bio-metallurgy a promising alternative for valorisation biological rout...

Abstract In the present study, AA7075/Al2O3 composites have been fabricated via liquid metallurgy process. AA7075 alloy and Al2O3 particles were taken as base matrix reinforcements, respectively. Then, contents of 3 6 wt. % subdivisions added into matrix. To improve wettability distribution, reinforcement pre-heated to a temperature 550°C for each composite sample. A hardened EN32 steel disc co...

The modern state of secondary metallurgy is characterized by the sustainable development technologies that ensure high metal quality reducing number non-metallic inclusions, which closely related to oxygen content in steel after smelting. Therefore, issues regularities distribution between phases at stage, BOF - CCM. Purpose. aim research was determine conditions redistribution dissolved depend...

Biomedical austenitic stainless steel (ASTM F2581) has been processed by the powder metallurgy technology using binder assisted extrusion method and aside a sintering aid. The resultant microstructure was examined optical microscopy, field emission scanning electron transmission microscopy x-ray diffraction methods. images indicate that aid considerably decreases porosities of sintered samples....

The physical and mechanical properties of samples of a nickel-base alloy fabricated by powder metallurgy were determined. The particle sizes of the powders used to make the samples varied from -80/ +200 mesh to -325 mesh. The compaction pressure varied from 138 to 414 MN/m2 and the sintering temperature varied from 1150 to 1250 degrees C. The shrinkage during processing, the porosity, tensile s...

C. Oprean, C. Tănăsescu, Lucian Blaga University of Sibiu, G. Dobrotă, Constantin Brâncusi University of Târgu Jiu This article aims at analysing whether the field of metallurgy in Romania is informationally efficient or not. This field is important for the real Romanian and world-wide economy, that is why the answer to this dilemma is important, and it will determine the investment behaviour o...
