摘要
常规镁合金的晶粒粗大、高温力学性能低、耐蚀性差,本文综述了Sr、Y合金元素对镁合金晶粒的细化作用、对镁合金的耐热性和耐蚀性的影响,并分析讨论其细化机理、提高镁合金的耐蚀性和耐热性的机理。
The conventional magnesium alloy shows the coarse grain,low mechanical properties under high temperature and poor properties of corrosion resistant. In this paper, the effects of Sr and Y alloying element on refining the grain of magnesium alloy, improving the resistant creep and the resistance corrosion of magnesium alloy were reviewed and the mechanism of relining,resistance of creep and corrosion analyzed and iscussed as well.
