In 1988, Li Weiyong took over the task of leader of the special group of the National Seventh Five-Year Plan Key Science and Technology Project "Research on High-Performance NdFeB Permanent Magnetic Materials" and developed high-performance permanent magnets with internationally leading levels. The total area reached 49 trillion, making my country one of the few countries in the world that can obtain this high-performance magnet. This achievement won the National Seventh Five-Year Science and Technology Major Achievements Award issued by the three ministries and commissions of the State Council, and was named my country's 1989 Metallurgical Year. One of the top ten scientific and technological achievements. He has also made important contributions in the development of high coercivity and low temperature coefficient rare earth permanent magnet materials and radially oriented NdFeB permanent magnet rings. While working at the Swedish Metal Research Institute from 1991 to 1992, he achieved new results in the research of a new generation of rare earth permanent magnet materials, which was highly praised by his peers at home and abroad. He has published more than 20 papers at home and abroad, including one first-class National Science and Technology Progress Award, three Science and Technology Progress Awards from the Ministry of Metallurgy, and two national invention patents. Since 1992, he has enjoyed the fifth "Chinese Young Scientist Award" as a special government subsidy. ” Nominated Award Winner. In 1995, he was selected as one of “the first batch of outstanding returnees who have studied abroad with key funding in the country” by the Ministry of Personnel, and was successively awarded the titles of “Young and Middle-aged Experts with Outstanding Contributions to the Country” and “Outstanding Scientific and Technological Youth in the National Metallurgical System”.
In May 2000, he was selected as a national model worker. In 2002, he was elected as a member of the National Committee of the Chinese People's Political Consultative Conference as a non-party member. Since 2007, he has served as a deputy to the National People's Congress. In 2010, he won the second prize of the Advanced Science and Technology Award of the People's Republic of China.
