摘　　要：采用电弧熔体快淬加后续晶化处理的方法批量制备了钕铁硼合金,研究了Zr、Nd元素含量对钕铁硼合金磁性能的影响。结果表明,添加的Zr原子能进入Nd2Fe14B相的晶格中,部分占据Nd原子的位置,从而提高Nd2Fe14B硬磁相的含量,因此显著提高(Nd,Zr)-Fe-B合金的磁性能。By arc-melt spinning and annealing, volume-production Nd-Fe-B alloys were mass-produced. Effects of Zr and Nd contents on the magnetic properties of Nd-Fe-B alloys were investigated. The experimental results show that partial Zr atom enters the Nd2Fe14B lattice and is in place of Nd atom position. So the addition of Zr can increase the practical Nd2Fe14B content, and the magnetic properties of (Nd, Zr)-Fe-B alloy are remarkably improved.
