Abstract Rapid solidification technology provides a possible route to prepare elevated-temperature aluminum alloys. Al–Fe–V–Si, Al–Fe–Mo–Si, Al–Fe–Cr–Ti, etc., series high-performance elevated-temperature aluminum alloys and their composites with heat resistance at temperatures of 300–400℃ have been successfully developed by rapid solidification/powder metallurgy process in nearly thirty years. In this paper, the developments in process, composition, microstructure, properties and applications for these elevated-temperature aluminum alloys and their composites are summarized, the existing problems and future directions are discussed.
