中文摘要：
首先对AZ31镁合金进行室温压缩，然后在不同温度和保温时间下进行退火，对其组织演变和再结晶动力学进行了研究。结果表明：可以用JMAK方程对其再结晶晶粒体积分数和时间的关系进行描述；初步计算出其再结晶激活能为85．1kJ·mol^-1左右；在300，350，400，450，500℃退火时的再结晶完成时间分别约为1599，380，112，40，16min。
英文摘要：
The cold compression of AZ31 Mg-base alloy was conducted and followed by annealing at different temperatures for different holding times. Microstrueture evolution and kinetics of static reerystallization was studied. The results show that the relationship between annealing time and volume fraction of the static recrystallization can be described by the JMAK equation. The activation energy was calculated to be about 85. 1 kJ · mol^-1 preliminarily. And the time for static recrystallization completion at 300, 350,400, 450, 500℃ was 1 599, 380, 112, 40, 16 min respectively.
