SMM survey: what kind of metal do you like most in 2022?

On December 3, 2021, the High Technology Research Center of the Ministry of Science and Technology organized the comprehensive performance evaluation meeting of the "13th five-year Plan" National key Research and Development Plan "key Technologies for Manufacturing large-size High-performance magnesium Alloy wrought Materials". The project manager, Academician of the Chinese Academy of Engineering, Professor Pan Fusheng of Chongqing University, responsible persons of five projects under the project, and researchers from Chongqing University, Metal Research Institute of Chinese Academy of Sciences, Shanghai Jiaotong University, Shanxi Yinguang Huasheng magnesium Co., Ltd., Beijing University of Technology, Northeast University, Beijing University of Science and Technology, Chongqing Changan Automobile Co., Ltd., and other project participants attended the meeting.

At the meeting, Academician Pan Fusheng, the head of the project, on behalf of the project team, made a comprehensive performance self-evaluation report to the expert group from the aspects of project background, project research content and objectives, research tasks and indicators, main achievements and benefits of the project, use of funds, organization and management, etc. After listening carefully to the report of the project team, the expert group watched the video display of the demonstration application of the project results, reviewed the relevant documents and materials, questioned the relevant questions, and made an overall evaluation and rating on the completion of the project. The expert group agreed that the project has fully completed the relevant work stipulated in the mission statement, met the expected objectives and assessment indicators of the project, and highly affirmed the remarkable results of the project in the research on magnesium alloy strengthening and toughening theory and common key technology. agreed that the project passed the comprehensive performance evaluation.

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 and supported by 34 million yuan of national special funds. Aiming at the "four aspects", aiming at the key technical bottlenecks and basic theoretical problems in the production and application of large-size wrought magnesium alloy products, the research on the new strengthening and toughening cooperative control mechanism and alloy design of magnesium alloy, the preparation of large size ingot and deformed material, residual stress reduction and surface protection were carried out, and the autonomous production capacity was established. The demonstration application of magnesium alloy products in transportation, aerospace, weapons and equipment, electronic information and other fields has been realized. The expert group believes that the research results make an important contribution to the major needs of countries such as aerospace, energy conservation and emission reduction, and are of great value to the main battlefield of national economic construction, such as lightweight vehicles and the competitiveness of the manufacturing industry. The project has formulated and approved a number of international standards and won two international awards, which has had an important impact on the international community and significantly enhanced the international voice of China's magnesium industry.
