Junpin Lin is engaged in research on dynamic recovery mechanisms of thermal deformation, hydrogen embrittlement, fracture micro-mechanisms and microstructure evolution of intermetallic compounds. In 1996, he worked as a senior visiting scholar at the Institute of Metal Physics, Urals Branch of the Russian Academy of Sciences for three months, and in 2001, he worked at West Virginia University for one year, as well as at the state Key Laboratory of Advanced Metal Materials, University of Science and Technology Beijing. He mainly focuses on the development, strong processing and nanostructure of intermetallic compounds (such as high NB-TiAl, Fe3Si, etc.) and new materials, the mechanism of liquid zinc corrosion of new materials, the mechanism of dynamic thermal deformation recovery of materials and the weld microstructure of beryllium and other metals.
