Cao Chunxiao, academician of Chinese Academy of Sciences, material scientist, one of the founders of titanium alloy research and application in China. He is currently a researcher and doctoral supervisor of AVIC Beijing Institute of aeronautical materials, professor and honorary director of Academic Committee of Nanchang Aeronautical University. At present, he is also a member of the Standing Committee of China Aviation Development Science and Technology Commission, member of the Advisory Committee of major special projects of large aircraft, member of the expert advisory group of COMAC, senior executive director of China Society of nonferrous metals, consultant of China Nonferrous Metals newspaper, and specially invited director of China Society of mechanical engineering Etc. He was the deputy director of the degree evaluation committee of China Academy of Aeronautics and the chairman of the degree evaluation committee of Beijing Institute of aeronautical materials, director of Academic Committee of Nanchang Aeronautical University, head of material science and engineering expert group of National Postdoctoral Management Committee, member of Expert Advisory Committee of national defense science and technology Commission, chairman of Plastic Engineering Society of China Society of mechanical engineering, titanium branch of China Nonferrous Metals Association President of the association, member of the Standing Committee of the Department of technology and science, Chinese Academy of Sciences, chief editor of materials engineering, etc. Cao Chunxiao has been developing innovative titanium alloys and titanium aluminum intermetallic compounds and their preparation technologies. According to the principle of combining recrystallization and phase transformation, the high and low temperature alternate hot deformation technology was established, which solved the key problem of uneven microstructure in the production of large titanium alloy parts for a long time; the special transformation mode was used to optimize the microstructure and comprehensive performance of titanium alloy beta transformation, and the BRCT heat treatment technology was initiated; the rapid cooling of titanium alloy was established by using the combined mechanism of deformation and phase transformation The basic problems such as strengthening mechanism, flame retardant mechanism and fatigue crack propagation characteristics of titanium alloy were studied, and creative achievements were obtained. As a result of the above achievements, it has successively won 16 national and ministerial level science and technology achievement awards, including 1 first prize and 3 second prizes of national science and technology progress award, and 2 third prizes of National Invention Award. He also published more than 200 papers at home and abroad. Five masters, 19 doctors and 6 postdoctors have been trained. In 1989, he was awarded the title of national young and middle-aged expert with outstanding contributions. In 1991, he was awarded the government special allowance. In 1993, he was awarded the first prize of Guanghua Science and technology foundation. In 1997, he was elected as an academician of Chinese Academy of Sciences. In 2001, he was awarded the National Gold Award (the highest award of the Department of aviation industry), in 2006, he was awarded the outstanding contribution award of aviation service to the country, and in 2012, he was awarded the China titanium industry In 2013, he won the lifetime dedication award of aerospace laurel award, and won the China Titanium Technology Lifetime Achievement Award in 2016.
