中文摘要：以AZ80镁合金轮毂的反挤压成形工艺为例，利用Deform有限元模拟软件，分别研究了不同压机速率、不同温度对AZ80镁合金反挤压高度的影响。通过对相同压机载荷下的不同反挤压高度的分析，得到了其在成形轮毂时的最佳压机速率为0.01～0.10 mm/s和成形温度段380~400 ℃，为后期AZ80镁合金的热成形性研究提供了一定的理论依据。
英文摘要：The anti-extrusion forming process of AZ80 magnesium alloy wheels was taken as an example to study the influence of press rates and temperature on the anti-extrusion height of AZ80 magnesium alloy based on software Deform. The different height values of anti-extrusion at the same load were researched. When the best velocity is 0.01～0.1 mm/s and forming temperature is 380~400 ℃, the formed wheels could be obtained. The results are significant for the hot forming study of AZ80 magnesium alloy.
