摘　　要：铝合金拥有比强度高、成本低、加工节能环保等特点,被广泛地应用于工业制造之中。在高强度铝合金的基础上发展出的耐热铝合金在高温下使用性能良好,抗疲劳系数大,因其密度低、高导热性等优良性能在航空、航天以及汽车行业中应用广泛。然而随着工业产业链的更新换代,耐热铝合金的实际应用需求也在快速增长,老一代高温耐热铝合金已不能满足工业需求,新一代高强度耐热铝合金因成本高、制备复杂等问题阻碍了其应用与发展,需要找到新的方法、工艺对合金进行强化。本文综述目前主流耐热铝合金耐热相的研究进展,阐述了耐热铝合金中耐热相的产生与调控,并展望了耐热铝合金的研究趋势与应用前景。Aluminum alloy has the characteristics of high specific strength, low cost, energy-saving and environmentally friendly processing, and is widely used in industrial manufacturing. The heat-resistant aluminum alloy developed on the basis of high-strength aluminum alloy has good performance at high temperatures and a large fatigue resistance coefficient. Due to its low density, high thermal conductivity and other excellent properties, it is widely used in the aviation, aerospace, and automotive industries. However, with the updating and upgrading of the industrial chain, the practical application demand for heat-resistant aluminum alloys is also growing rapidly. The old generation of high-temperature heat-resistant aluminum alloys can no longer meet industrial needs, while the new generation of high-strength heat-resistant aluminum alloys is hindered in their application and development due to high cost and complex preparation. It is necessary to find new methods and processes to strengthen the alloys. This article reviews the research progress of mainstream heat-resistant aluminum alloy heat-resistant phases, elaborates on the generation and regulation of heat-resistant phases in heat-resistant aluminum alloys, and looks forward to the research trends and application prospects of heat-resistant aluminum alloys.
