摘要：
With the rapid development of the aerospace industry, the demand for high-performance heat-resistant aluminum alloys will continue to increase in the future. In order to realize the one-step molding of complex components, laser powder bed fusion (L-PBF) additive manufacturing technology has become a hot research topic. The building parts manufactured by L-PBF additive manufacturing have a better overall performance than conventional casting manufacturing. At present, the researches on room-temperature high strength-ductility aluminum alloys are relatively comprehensive, but the researches on heat-resistant aluminum alloys are still in the initial stage. This review firstly introduces the L-PBF additive manufacturing technology, then summarizes the research on heat-resistant aluminum alloy systems and corresponding high-temperature properties in recent years, presents a brief overview of the current problems and challenges, finally looks forward to the main research interests in the future. © 2024 Cailiao Daobaoshe/ Materials Review.
