The recycling of high Fe-content Al-Si alloys is a green industry.Eliminating the harmful effect of Fe,achieving the separation of A1 and Fe is one of the key problems.Different from traditional methods for iron removal,a novel method using magnesium melt to separate A1 and Fe is proposed.By introducing Al-14Si-5Fe alloy into Mg melt,it was found that the γ-Al3.sFeSi phase evolves to Al3SiFe3.5 and Al5Fe2 through the melting and solidification process.Compared with the primary Al-rich γ-A13.5FeSi phase,the formation of Fe-rich A13SiFe3.5 is quite beneficial for the separation of A1 and Fe.Mg-Si-A1 and Mg-Si-Fe alloys can be obtained at the top and bottom of the cooled ingot,respectively.The results in this study provide meaningful suggestions for recycling scrap A1-Si-Fe materials.
