摘要(Abstract)：

采用Gleeble-1500热模拟试验机对铸态Mg-5Sm-1Gd合金在变形温度为350～500℃及应变速率为0.01～1s~(-1)的条件下进行了热压缩实验,构建了合金的高温塑性变形的本构方程,建立并分析了合金的热加工图。结果表明:Mg-5Sm-1Gd合金在热变形过程中有动态再结晶行为发生,合金的峰值应力及流变应力都随着应变速率的升高和变形温度的降低而升高,合金的热变形激活能Q=201.967kJ/mol;合金在T=430～500℃、■区域内的能量耗散率大于30%且不发生失稳,适合进行热加工。

关键词(KeyWords)： Mg-5Sm-1Gd合金;热压缩;本构方程;热加工图
