| 摘 要： | 采用透射电镜和扫描电镜对高合金化的ＺＡｌＳｉ６Ｃｕ２Ｍｇ合金在高温（１７０～３００℃）、短时（５～３０ｍｉｎ）条件下的微观组织变化及其对力学性能的影响进行了研究。结果表明，加入一定量的合金元素不仅提高了合金的室温力学性能，而且还能抑制在高温下Ｍｇ２Ｓｉ相的聚集长大，有利于提高合会的热强性。

| Abstract: | The microstructures and mechanical properties of high temperature and short exposing time tensilesamples of cast AlSi6Cu2Mg alloy are analyzed by TEM and SEM. With appropriate content alloyimg ele-ments, the mechanical properties of the alloy at room temperature, meanwhile,the high temperaturestrength can be improved due to retardation of accumulation and growth of Mg2Si phase. |
