| Abstract Scope |
Iron is unavoidable but detrimental in Al alloys as it forms plate- or needle-like Fe-containing intermetallic compounds (FIMCs). Developing a new type of Al alloy with higher Fe tolerance will be beneficial for the performance of these Al alloys. This study screens a wide compositional range of Al-Mn-Fe-Si alloys to investigate the Fe effects using combinatorial alloy synthesis by laser directed energy deposition (DED) additive manufacturing (AM). Seven Al-Mn-Fe-Si alloys featuring different levels of Fe were deposited by DED under different substrate cooling rates. A series of heat treatments were conducted to study the particle evolution and phase transformation, followed by the small-scale tensile testing. The results indicate that the high cooling rate of AM increases the Fe tolerance of these alloys. |
