Long-term engaged in the research of new materials and processes such as superalloys and non-equilibrium alloys. Successfully developed China's first-class hollow turbine blade materials and civil aviation long-life blade materials; Directional crystallization blades, directional crystallization cobalt-based alloy blades and special microcrystalline powder with thermal corrosion resistance have been successfully developed. Successfully developed the first supercharger for helicopters in China; The theory of non-equilibrium redistribution of solute in constrained solidification process is put forward. It has successively won the second prize of National Science and Technology Progress Award, the first, second and third prizes of Science and Technology Progress Award of China Academy of Sciences, and more than one provincial and ministerial award 10, among which "Development and popularization of porous air-cooled cast first-class turbine blades for engines" won the first prize of National Science and Technology Progress Award.
Published 4 1 1 papers abroad, 366 papers, 4 monographs, 5 translations and 4 patent applications in China. Train 60 doctoral students. He has successively won the honorary titles of Liaoning Model Worker, Liaoning Excellent Expert, Shenyang Honorary Expert and Shenyang Branch of Chinese Academy of Sciences Excellent Postgraduate Tutor.
