摘要 由于拉压不对称性对镁合金成形有重要的影响,如何减弱不对称性是当前研究的一个主要课题目。综述了拉压不对称产生的机理,阐述了晶粒尺寸、加载方式、热处理、合金元素以及工艺参数如温度和应变速率对镁合金拉压不对称性的影响,以寻求一个简单有效弱化拉压不对称性的方法和手段。提出了镁合金拉压不对称性存在的问题以及发展趋势。 As tension-compression asymmetry has an important effect on the forming of magnesium alloy, how to reduce asymmetry is one of the main subjects of current research. Mechanism produced by tension-compression asymmetry was summarized. The effects of grain size, load direction, heat treatment, alloy element and the process parameters like such as temperature and strain rate on the tension-compression asymmetry were expounded to fend a simple and effective method and means of weakening the tension-compression asymmetry. Problems and the development trend of tension-compression asymmetry of magnesium alloy were presented.
