中文摘要：本文主要研究了异步轧制对AZ31镁合金晶粒细化的影响，以探讨提高AZ31镁合金板材深冲性能的途径。结果表明，异步轧制能显著的细化晶粒，且一定程度上能减弱（0002）基面织构，但随着晶粒的细化，杯突值、最大冲压力都逐渐降低，制耳现象越来越严重。
英文摘要：This paper mainly studies the asynchronous rolling AZ31 magnesium alloy grain refinement, in order to investigate the way of improving ductility enhancement in AZ31 magnesium alloy plate deep-drawing performance .the results showed that asynchronous rolling can significantly refined grain , can be reduced (0002) basal plane texture in some degree, but with the structural grain refinement, cupping value, the maximum punch pressure are gradually reduced , the ear phenomenon is more and more serious.
