摘要(Abstract)：

通过光学显微镜、扫描电镜分析了铸态及固溶处理态Mg93Zn6Y1合金的显微组织,并利用EDS、XRD进行了物相分析。结果表明,铸态Mg93Zn6Y1合金的显微组织主要由α-Mg相和准晶相(Mg3Zn6Y1)组成。此外,差热分析(DTA)用来分析其相变,得到Mg93Zn6Y1合金合适的固溶温度为430℃。研究发现固溶处理后,Mg93Zn6Y1合金中准晶相发生熔断,由铸态下的连续网状结构变为颗粒状。通过阻尼性能测试以及腐蚀速率测试,发现固溶处理可以较好地改善Mg93Zn6Y1合金的阻尼性能以及耐蚀性能。

关键词(KeyWords)： Mg93Zn6Y1合金;准晶相;固溶处理;阻尼性能;耐蚀性能
