摘要
Abstract
This paper introduced the characteristics of Mg-Al alloys,reviewed the influence and mechanism of C,Sr,Ti,and RE elements on the metamorphic refinement of Mg-Al alloys.By the AZ,AM,AS and AE alloy systems,the differences under different metamorphic treatments were compared.The optimal dosage,addition temperature and holding time of the metamorphic agent were pointed out.The influence of the metamorphic agent on the grain size,microstructure evolution and mechanical properties of the alloy were summarized,which provided a reference for the metamorphic refinement of Mg-Al alloys.Finally,the author summarized the characteristics of metamorphic agents in several types of alloys,and provided systematic ideas for the preparation of high-performance and low-cost magnesium alloys.关键词
