| Abstract Scope |
Primary aluminum production is highly energy-intensive and generates significant greenhouse gas emissions. The growing availability of recycled aluminum scrap presents an opportunity, however, controlling common impurity elements in such scrap is challenging. Specifically, Fe and Si impurities often form large and brittle Fe-intermetallic phases that are detrimental to the ductility of aluminum alloys. This issue is especially pronounced in Al-Mg alloys. To address this challenge, we performed high-throughput thermodynamic calculation using improved thermodynamic models to design a novel family of Al-Mg alloys that can tolerate Fe and Si impurity levels exceeding 0.5 wt.% while maintaining or enhancing ductility. The newly designed Al-Mg-Fe-Si alloys significantly promote the usability of recycled materials in automotive applications. |
