Present society challenges, including metal scarcity, recycling, and environmental restrictions, resulted in the increased complexity variability of metallurgical feed streams. Metallurgical processes involving complex lead copper-containing slag matte phases are now commonly used response. Optimization existing development new require fundamental information on slag–matte phase equilibrium. De...

Metallurgical slag, including ferrochrome slag is internationally recognized as suitable material for use in road construction and as aggregate for concrete (Rossouw et al. 1981, Lind et al. 2001). Contrary to international practice, metallurgical slag – including ferrochrome slagis classified as hazardous waste that must be de-listed before use in other applications (DWAF 1998). Having adopted...

Abstract The current investigation of refill friction stir spot welding (refill FSSW) Al alloy to copper primarily involved plunging the tool into bottom sheet achieve both metallurgical and mechanical interfacial bonding. Compared conventional FSSW pinless FSSW, weld strength can be significantly improved by using this method. Nevertheless, wear is a critical issue during FSSW. In study, defec...

Heavy metal contamination of soil and plants is a worldwide concern. Cop?a Mic? in Romania one the areas country known to have high level pollution. Even if metallurgical activities been reduced or stopped still polluted. This study aimed estimate bioaccumulation heavy metals (Cd, Pb, Zn Cu) from garlic bulbs (Allium sativum L.) individual gardens polluted area, Romania. The was estimated based...

A novel multi-material design concept to be applied in plastic injection moulds is proposed combining the mechanical resistance of 420 stainless steel alloy and high thermal conductivity copper, a single component, fabricated just one event by means homemade 3D Multi-Material Laser Powder Bed Fusion equipment. The processing strategy interface region between both materials are analysed discusse...

The analyzes of six samples slag found during urban development works in the city Ibiza (Balearic Islands) are presented. These samples, which one first analyzed from old town town, correspond to products a metallurgical workshop dedicated bronze industry. three be discussed remains ternary metallic elements (copper, tin and lead) production phase. metals would mixed ceramic vessels (crucibles)...
