摘要
快速凝固技术为高温铝合金的制备提供了可能的途径。近30年来,运用快速凝固/粉末冶金工艺,已研制成功了Al-Fe-V-Si、Al-Fe-Mo-Si、Al-Fe-Cr-Ti等系列的耐热温度达到300~400℃的高性能高温铝合金及其复合材料。总结了这些高温铝合金及其复合材料在工艺、成分、组织、性能和应用方面的研究进展,讨论了存在的问题并阐述了未来的发展方向。
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.
