摘　　要：评述了国内外细化AZ91D镁合金晶粒的方法(碳质孕育法、添加合金元素法、机械变形处理法、半固态成形法),以及通过复合增强及热处理方法(均匀化退火、固溶处理、人工时效、二次热处理、表面热处理)提升AZ91D镁合金性能的机制。对其发展前景进行了展望。The methods of refining AZ91 D magnesium alloy grains at home and abroad were expounded in this paper, such as carbonaceous inoculation, adding alloying element, mechanical deformation treatment, and semi-solid forming process. It was also stated how to improve the properties of AZ91 D magnesium alloy by compound strengthening and heat treat- ments. The heat treatment methods include homogenizing annealing, solid solution treatment, artificial aging, secondary heat treatment and surface heat treatment. Its development was prospected as well.
