摘　　要：耐热铝合金由于具有低密度、低价格、良好的耐热和耐腐蚀性能,在航空、航天等工业领域得到了广泛应用。回顾了耐热铝合金的发展历程,重点阐述了耐热铝合金的组分选择原则、制备方法及强化机制。分析了其目前存在的问题,并对今后的发展动向进行了展望。Heat resistant aluminium alloys have been used in the aircraft industry widely because of their attractive combination of light weight, low cost, heat resistance and corrosion resistance. In this paper, the development of rapid-solidified heat resistant aluminum alloys are reviewed, and the principle of compositional selecting, preparation methods and reinforcement mechanism are analyzed emphatically. The problems in the development of the alloys are analyzed. Some points of view on the development trend are proposed.
