摘要：

The coercivity of the sintered Nd-Fe-B permanent magnets prepared by the dual-main-phased (DMP) process can be significantly enhanced. This paper provides a comprehensive review of this method. The methodology and process of the DMP method are outlined, along with its mechanisms and advantages in improving magnet performance. Furthermore, this study highlights the outstanding performance of DMP magnets in terms of mechanical properties and corrosion resistance. Lastly, the future development trends and research directions for the DMP method are explored, such as optimizing process parameters, exploring novel alloy designs, and developing higher-performance magnet materials.
