摘 要: | Nd-Fe-B磁粉的各向异性是当前日益引人关注的一个问题,对Nd-Fe-B磁粉各向异性形成机制的研究有助于获得高性能各向异性粘结磁体。也有助于进一步揭示Nd-Fe-B磁硬化机制,本文对Nd-Fe-B-Co-M(M=Ga,Nb)系进行了较为系统的研究,发现磁粉的BτⅡ(平行于成形磁场方向)比Br⊥(垂直于成形磁场方向)大了近1倍,说明Nd-Fe-B-Co-M系的HDDR磁粉具有较强的各向异性,进一步

Abstract: | The properties of Nd Fe B Co M (M=Ga,Nb) HDDR powders are studied systematically. The results show that the anisotropy of these powders can be in creased by adding Ga, and the best disproportion ationtemperature of Nd Fe B Co Ga is higher than that of Nd Fe B Co. |
