摘要
讨论了镁合金抗高温蠕变机理和提高镁合金抗高温蠕变的途径,重点介绍了Mg-Al系、Mg-Zn系和Mg-RE系耐热铸造镁合金的研究现状;对高性能耐热镁合金的发展趋势提出了一些见解,认为应该进一步优化合金元素,以解决铸造镁合金在耐高温、抗蠕变等方面存在的问题。
The mechanism of creep resistance at elevated temperatures of magnesium alloys and the method to improve the resistance of the alloys are discussed with the present status of the researches of the heat resistant cast alloys （Mg-Al, Mg-Zn, and Mg-RE） highlighted. Some thoughts about the development trend of the alloys with excellent properties are described. It is concluded that in order to solve the problems existing with the heat and creep resistance of the cast alloys, the alloying elements must be optimized.
