摘　　要：针对AZ31镁合金平板的轧制过程进行试验研究,通过控制温度及不同道次的压下率等工艺条件,最终将36mm厚的镁合金铸锭,压制成厚度为1mm的板材。同时运用MSC.Marc软件,采用显式弹塑性有限元法对AZ31镁合金平板的轧制过程进行热-机耦合三维数值模拟。对轧件在轧制过程的金属流动、温度、应力及应变分布等特点进行分析,并与实际试验结果进行对比,验证了模拟结果的准确性。Using experimental method, the rolling process of the AZ31 magnesium alloy was investigated, in which a 1 mm thickness sheet was successfully make out from a 36mm thickness cast ingot by controlling the temperature and reduction in pass. In order to learn the metal flowing, temperature, strain and stress distribution characteristics, the hot-mechanical coupling three-dimensional numerical simulation of the rolling process was simulated. The simulation results are in agreement with those of experiments.
