摘要
综述了高温使用烧结 Nd-Fe-B 磁体的研究现状,总结了制作高温烧结 Nd-Fe-B 磁体常用的3务途径,即提高居里温度、磁晶各向异性场和优化磁体显微组织。这三项措施一般需同时使用,以获得综合性能良好的耐高温磁体。
Recent development of sintered Nd-Fe-B magnets used at high temperatures is reviewed in this paper.There are three possible approaches to produce these magnets,increasing curie temperature(T_c),enhancing anisotropy field(H_A)and improving microstructure.These approaches should be used synchronously to obtain sin- tered Nd-Fe-B magnets with satisfactory properties for high temperature employing.
