Abstract Scope |
Production of Al alloys from end-of-life (EoL) scrap is accompanied by increased Cu and Fe contents, as these cannot be economically removed from the melt. Within the scope of this investigation, based on CALPHAD simulations, Cu- and Fe-containing alloy variants of AlSi7Mg0.3 were produced at laboratory scale using gravity die casting. Microstructural analyses and tensile tests were carried out in the as-cast state. The alloys were examined, characteristics quantified, and interactions revealed and compared with the base alloy. It is shown that Fe and Cu contents above the known limits of the common delivery specifications can result in good mechanical properties. Hardness, yield strength and tensile strength can correspond to the level of the base alloy and cause only minor losses in elongation. |
