摘要
采用高能球磨的方法，按照Sm含量以及不同的球磨时间来制备（Nd，Sm）FeB粉体试样，最后通过强磁场取向原理将（Nd，Sin）FeB粉体试样制成（Nd，Sm）FeB取向试样，利用VSM对性能进行研究。结果发现，通过高能球磨法和强磁场取向原理制取的（Nd，Sm）FeB试样，其矫顽力、剩磁等磁性能随着球磨时间延长而呈现出先下降后上升的趋势；而当含量变化时，取向试样的矫顽力、剩磁等磁性能又会呈现出随Sm元素含量增加而线性下降的趋势。
Adopt the method of high--energy ball mill, according to the content of Sm and different ductile time to prepa- ration （Nd, Sm） FeB powder sample, finally through a strong magnetic field orientation principle will, Nd, Sm） FeB powder specimen made （Nd, Sm） FeB orientation. On this basis, VSM analysis to the original NdFeB specimen and （Nd, Sin） FeB o- rientation of performance and organization are studied. It was found that by high energy ball mill and strong magnetic field ori- entation principle, Nd, Sm） FeB sample, the coercive force, remanence magnetism can be prolonged with the ball mill and presents the decline after the first rising trend; When content changes, the orientation of the sample of coercive force, rema- nence magnetic and can present a linear downward trend with the increase of Sm element content.
