摘　　要：Al-Cu-Mg-Ag合金具有高温高比强度、抗蠕变、抗氧化等优点及良好的加工性能,是有望部分取代钛合金应用在300~400℃的一种耐热铝合金。近年来,为了进一步提高Al-Cu-Mg-Ag系合金的高温力学性能,通过微合金化、复合化和工艺改进等方法改变了合金的显微组织和力学性能,取得了一定的研究进展。为此对Al-Cu-Mg-Ag系耐热铝合金的研究进展进行综述,结果表明:微合金化法主要通过对Ω相热稳定性的改进作用和引入新型高热稳定性强化相而提高高温性能;复合化方式通过外加高热稳定性强化相提高高温力学性能;工艺改进主要通过优化合金显微织构提高高温性能。Al-Cu-Mg-Ag alloy has high specific strength at high temperature,creep resistance,oxidation resistance and good machining performance.It is a kind of heat resistant aluminum alloy that is expected to partially replace titanium alloy in 300℃to 400℃.In recent years,in order to further improve the mechanical properties of Al-Cu-Mg-Ag alloys at high temperature,some research progress has been made by changing the microstructure and mechanical properties of Al-Cu-Mg-Ag alloys through microalloying,compounding and process improvement.In this paper,the research progress of Al-Cu-Mg-Ag series heat-resistant aluminum alloys is reviewed.The results show that the microalloying process can improve the high temperature performance mainly by improving the thermal stability ofΩphase and introducing a new high thermal stability strengthening phase.The high temperature mechanical properties are improved by applying high thermal stability strengthening phase.The high temperature properties of the alloy are improved by optimizing the microstructure.
