摘　　要：综述了热挤压、轧制、大塑性变形挤压等不同塑性变形工艺在变形镁合金晶粒细化中的应用研究进展,认为目前变形镁合金发展的主要瓶颈是低加工速率导致相关产品的成本居高不下,未来将通过大尺寸半连续铸锭的多外场晶粒细化和细晶镁合金快速加工技术等予以解决。In this paper, the applications of different various plastic deformation processing, such as hot extrusion, rolling and large plastic deformation, on grain refinement of wrought magnesium alloy were reviewed systematically. The high cost of related products caused by low processing speed has been regarded as one of the main factors limiting the development of wrought magnesium alloys. But in the future, this problem can be solved by semi-continuous casting preparation of large size using multi-outfield and rapid processing of fine grained magnesium alloys.
