Research and production of NdFeB magnets associated with Zhejiang University

In the talk, the present research and production status of NdFeB magnets in China is outlined. The main research on NdFeB magnets at Zhejiang University is presented. The microstructural restructuring of grain boundaries of sintered NdFeB is focused. Through microstructural restructuring, the corrosion resistance of sintered NdFeB can be effectively improved, and NdFeB magnets with high coercivity and low heavy RE contents can be fabricated.
