| Abstract: | Complex and high-precision parts can be manufactured rapidly by selective laser melting (SLM) technology, which has great development potential in aerospace and industrial production. Lightweight manufacturing of structural materials can be realized by high-strength aluminum alloy, which has a rapid development in field of selective laser melting in recent years. The research status and development trend of SLM-fabricated Al-Mg-Sc high-strength aluminum alloys from three aspects of alloy composition, microstructure and mechanical properties was comprehensively summarized in this paper. More attentions on strengthening elements diversification, microstructure development and performance characteristics in SLM-fabricated Al-Mg-Sc high-strength aluminum alloys should be focused in the future development. |
