Abstract Scope |
The production of Al alloys from end-of-life (EoL) scrap is being accompanied by increased Fe-, Cu- and Zn content. The influence of these elements was evaluated with special emphasis on phase formation, via the application of CALPHAD methods to address the questions if a defined heat treatment can compensate for the formation of Al9Si2Fe2 and Al2Cu, how the combinations of such elements influence the formation of detrimental phases and whether a combined approach of heat treatment and alloy design is valid for higher amounts of Fe, Cu and Zn in primary based alloys.
It was found that Cu and Zn up to established limits in common supply specifications are less detrimental to alloy properties. Fe was found to be manageable which is in good agreement with previous findings. |
