Abstract Scope |
The unique combination of properties like high strength-to-weight ratio, excellent castability, thermal & electrical conductivities, and outstanding corrosion resistance enables aluminum alloys to be widely used in diverse industries. Because of its high recyclability, aluminum is a material of choice for a circular economy. However, during recurring scrap recycling, aluminum recycling can be complicated by the gradual accumulation of unwanted impurities, mainly Fe, Mn, and other (Cu, Si, Zn, and Mg) alloying elements. The impurity pickup can result in significant economic devaluation of scrap where aluminum products are downcycled to produce aluminum products with lower value and performance. Managing the impurity content of aluminum scrap melt is therefore very important. In the present study, the simultaneous removal of Fe and Mn was studied from aluminum alloys via an intermetallics sedimentation route. ThermoCalc is used to determine the suitable temperature for impurity-rich intermetallic phase formation in experimental alloys. |
