Design, microstructure and thermal stability of a novel heat-resistant Al-Fe-Ni alloy manufactured by selective laser melting

Selective laser melting (SLM) technology is promising to fabricate complex-shaped metal components, especially light-weight aluminum (Al) alloy. Facing the grow requirement of thermal stability for applications in aviation and aerospace at high temperatures, the poor thermal stability of Al alloy needs to be improved. Thus, in this study, we developed a novel heat-resistant eutectic Al-Fe-Ni alloy which is suitable for the SLM process. Firstly,...
