摘 要: 介绍了制备NdFeB磁粉的HDDR工艺,重点分析了HDDR NdFeB磁粉各向异性形成的“残余核模型”和“中间相理论”及磁体的矫顽力机理。 The HDDR processes of preparing NdFeB magnetic powders have been introduced. The "remnant nuclei model" and "intermediate phase theory" of the anisotropy form of magnetic powder and the coercivity mechanism of HDDR NdFeB magnet were analyzed carefully.
