To further promote the applications,in this paper,the applications of magnesium alloys are reviewed,which could provide insights for researchers and application designers. Firstly,the applications in aerospace are reviewed,including missile,satellite,rocket,and spacecraft.Secondly,the applications and commercial magnesium alloys in aviation are summarized. Thirdly,the bottleneck and existing problems for such magnesium alloys applied in aerospace and aviation are discussed. The requirements for the magnesium alloy performance in aerospace and aviation are evaluated and elaborated.展开更多
