Jiang Chengbao, born in September 1968, is an academician of the Chinese Academy of Sciences. His research field is magnetic functional materials. He has served as the Dean of the School of Materials Science and Engineering at Beihang University, and the Director of the Key Laboratory of Aerospace Advanced Materials and Services under the Ministry of Education. He also holds a standing director position in the China Materials Research Society. He has long been engaged in the functional regulation, material preparation, and engineering application research of high-performance rare earth magnetic materials. He has led projects such as the National Natural Science Foundation's Innovative Group Project, the National Natural Science Foundation's Major Instrument Project, and Major National Innovation Project. He proposed a new mechanism for the magnetostriction effect of nano-heterostructures and invented large strain iron-based giant magnetostrictive materials; he solved the important problems of narrow temperature range and corrosion resistance of rare earth giant magnetostrictive materials, and prepared high-performance rare earth giant magnetostrictive crystalline materials; he invented high-temperature resistant and oxidation-resistant high-performance rare earth permanent magnetic materials. The high-performance magnetic materials developed by him are used in important fields. Over 300 academic papers have been published, and more than 40 national invention patents have been granted. The team has also won the first prize of National Invention Technology (ranked 2nd), the second prize of National Natural Science (ranked 1st).
