摘要：
The recent research progress of the NdFeB-type nanocrystalline two-phase composite permanent magnetic materials is reviewed. The effects of the alloy composition or Nd:Fe:B ratio, the addition of various transition alloying elements, and the processing route and parameters on the microstructure and magnetic properties have been discussed and summarized. Also, both the dependence of magnetic exchange coupling on microstructure and its effect on the magnetic properties has been presented.
