The evaluation meeting of the national key research and development plan of wrought magnesium alloy was held.

Recently, led by Chongqing University, Pan Fusheng, academician of the Chinese Academy of Engineering and director of the National magnesium Alloy Materials Engineering and Technology Research Center, was responsible for the "13th five-year Plan" national key R & D project "key technologies for the manufacture of large-size and high-performance magnesium alloy wrought materials". The performance evaluation meeting was held. The meeting was conducted both online and offline. Li Hejun, academician of the Chinese Academy of Engineering and professor of Northwestern Polytechnic University, served as the leader of the project performance evaluation group. Mou Xiaoyun, deputy director of Chongqing Municipal Bureau of Science and Technology, and Mingju, vice president of Chongqing University, attended the meeting. The meeting was presided over by Zhu Caichao, dean of the Institute of Science and Technology Development of Chongqing University.

The national key R & D program consists of the original national key basic research and development plan (973 plan), the national high-tech research and development plan (863 plan), the national science and technology support plan, the international scientific and technological cooperation and exchange project, the industrial technology research and development fund and the public welfare industry scientific research project and so on. The project focuses on the key manufacturing technologies of large-size and high-performance magnesium alloy wrought materials, with the goal of solving the core competitiveness of the high-end magnesium alloy industry. The project consists of five projects, which are respectively undertaken by Chongqing University, Institute of Metals, Chinese Academy of Sciences, Shanghai Jiaotong University, Shanxi Yinguang Huasheng magnesium Co., Ltd. And Beijing University of Technology. After five years of work, various research groups have comprehensively completed the task objectives of the project and achieved a number of important results. According to the requirements of the Ministry of Science and Technology, the project performance evaluation group is composed of Li Hejun, Zhou Kechao, professor of Central South University, Chen Jialin, researcher of Kunming Precious Metals Research Institute, Shan Zhiwei, professor of Xi'an Jiaotong University, Wang Tongmin, professor of Dalian University of Technology, Liu Ying, professor of Sichuan University, Cui Hongzhi, professor of Shandong University of Science and Technology, Liu Xiangfa, professor of Shandong University, and Deng Yida, professor of Tianjin University. Li Hejun is the group leader.

Mingju first delivered a welcome speech on behalf of the conference organizing unit, thanking the leaders and experts who participated in the topic performance evaluation meeting. Mou Xiaoyun introduced the basic situation of Chongqing's scientific and technological innovation measures and undertaking national science and technology plan projects, and hoped that the research group would take this evaluation meeting as an opportunity to further refine the results and identify problems and deficiencies. Pan Fusheng briefly introduced the background and significance of the project, the project research team, the implementation of each project and the main achievements. Du Wenbo, a professor at Beijing University of Technology, Wang Jingfeng, a professor at Chongqing University, Dong Jie, a professor at Shanghai Jiaotong University, Le Qichi, a professor at Northeastern University, and Yang Yuansheng, a researcher at the Institute of Metals, Chinese Academy of Sciences, respectively represented five research groups. Report to the expert group on the comprehensive performance evaluation of the project from the aspects of the background and significance of the project, the research task, the completion of goals and indicators, the main achievements and benefits of the project, the use of funds and the organization and management of the project. After listening to the reports of each research group, the experts asked questions on the relevant issues, and made an overall evaluation and rating on the completion of each project. The expert group agreed that various topics have well completed the research tasks and assessment indicators, with outstanding results and remarkable results. The expert group put forward valuable opinions and suggestions on the further improvement of the project performance evaluation data, and put forward new expectations for the further R & D work of the project unit in the future.

Finally, Pan Fusheng made a concluding speech, expressed heartfelt thanks for the work and guidance of the expert group, and put forward requirements for the follow-up comprehensive performance evaluation of the project. all research groups are required to further revise and improve the subject and project performance evaluation materials in accordance with the requirements of the expert group, and hope that all participating units will continue to unite and cooperate to further promote the research and development and application of magnesium alloys.

The national key R & D project, "key Technologies for Manufacturing large-size and High-performance magnesium Alloy wrought Materials", was approved in July 2016, led by Chongqing University. Institute of Metals, Chinese Academy of Sciences, Shanghai Jiaotong University, Shanxi Yinguang Huasheng magnesium Co., Ltd., Beijing University of Technology, Northeast University, Harbin University of Technology, Beijing University of Science and Technology, Central South University, Zhengzhou University, Jilin University, Zhongbei University, Beijing University of Aeronautics and Astronautics, Northeast Light Alloy Co., Ltd., Western Titanium Industry Co., Ltd., China Baowu Iron and Steel Group Co., Ltd., Chongqing Changan Automobile Co., Ltd., Shanghai Aerospace equipment Manufacturing General Factory, Shanghai Satellite Engineering Research Institute, Longkou Jungle Aluminum Co., Ltd. Through the implementation of the project for 5 years, the new strengthening and toughening synergistic regulation mechanism of magnesium alloy is revealed, the new strengthening phase design theory and large volume melt purification theory are developed, and the rheological behavior and deformation mechanism of ultra-high strength / large size alloy are clarified. the formation and distribution of residual stress are revealed. It has formed a number of key technologies for the preparation, processing and application of large-size and high-performance magnesium alloy deformation materials, such as high-alloy and high-purity ingots, high strength and toughness profiles and forgings, high-precision strip coils, stress reduction of deformed materials and surface protection; the results of the project have achieved application and demonstration in key industries and major projects, resulting in remarkable economic benefits and energy saving and emission reduction effects, and made an important contribution to the upgrading and progress of China's magnesium industry.
