High-strength heat-resistant magnesium alloy material and its application in aerospace technology development Main Completed by: Wu Guohua, Ding Wenjiang, Zeng Xiaoqin, Peng Liming, Wang Yingxin, Dong Jie, Wang Dudong, Guo Xingwu, Jiang Haiyan, Liu Wencai Major Completed by: Shanghai Jiaotong University With the urgent demand for light weight in the field of aerospace, lightweight high-strength heat-resistant magnesium alloy has become a hot topic and a focus of competition in advanced materials technology. However, there are some shortcomings of magnesium alloy materials such as small selection range, low strength, poor heat resistance, difficult purification, poor moldability and backward technology and equipment, which seriously hampered the lightweighting of aerospace equipment and the improvement of flight targets. The project has made a series of creative achievements in the development of high-strength heat-resistant magnesium alloy materials and their application technologies,
