At 13:25 on July 23, 2020, China’s first Mars exploration mission "Tianwen-1" on the Long March 5 Yaosi carrier rocket successfully launched at the Wenchang Space Launch Site, successfully entered the scheduled orbit, and started Mars exploration. The brigade took the first step in China's planetary exploration.
This time, the "Tianwen No. 1" Mars probe applied the world's lightest metal structure material: high-performance magnesium-lithium alloy developed by HNXJ Light Alloy Material Technology Group.
Professor Chai Donglang, the chief researcher of HNXJ, used to be the director of the Typical Parts Heat Treatment Technical Committee of the Chinese Society of Heat Treatment, the director of the Physical Metallurgical Technology Committee of the Chinese Society of Materials and Heat Treatment, and the honorary chairman of the Shaanxi Society of Materials and Heat Treatment; successively won the third prize of National Science and Technology Progress Award and education Ministry of Science and Technology Progress Second Prize, Shaanxi Province Aviation Technology Outstanding Talent Award, Special Contribution Award of the Heat Treatment Branch of the Chinese Mechanical Engineering Society, etc.; presided over the drafting of 2 national standards, 2 national military standards, and more than 20 national and provincial-level projects. Published more than 70 academic papers.
New materials are an important basic and leading industry of the national economy, with high technical content, high added value, and a wide range of applications. They are key areas that promote the supporting development of various sectors of the Chinese economy and support China’s leap from a manufacturing power to a manufacturing power. . Professor Chai Donglang has devoted his life to the basic theoretical research and industrial development of new materials for more than 30 years. In addition to the "Tianwen No. 1", his scientific research results are still on the "Pujiang No. 1" satellite and the first global carbon dioxide monitoring science. Among the experimental satellites, high-resolution micro-nano satellites, "Communication Technology Test Satellite III" and other spacecraft have been successfully applied.
