| 摘 要： | 主要研究了在烧结ＮｄＦｅＢ磁体的晶界添加Ｗ对显微组织和磁性能的影响，实验结果表明，随Ｗ添加量的增大，晶粒逐渐细化，剩磁稍有下降，面矫顽力逐渐升高，在含Ｗ为１％ｗｔ时，矫顽力达到峰值。扫描电镜的观察显示，加Ｗ磁体在晶界区生成许多杆状相，能谱和Ｘ线射线衍射分析均表明此相为ＷＦｅＢ化合物。

| Abstract: | The addition of W to the intergranular region of NdFeB sintered magnets was found to bring a substantial increase in coercivity, and reductions in remanence and grain size, the highest coercivity corresponds to amount of 1% wt W addition. SEM observation revealed that new WFeB compound with colony like phase appears at grain boundaries. |
