摘　　要：利用球磨法制备Sm2Fe17N2 9粉体,利用X射线衍射仪、比表面积分析仪、扫描电镜、透射电镜、振动样品磁强计、交流初始磁化率测定仪等实验仪器和测量分析方法,对所制备的Sm2Fe17及氮化物的磁性能进行了分析.实验结果表明:球磨法所制的样品质量配比数较为合理,样品在500℃氮化3h磁性能为最佳,主相为TH2Zn17的菱方结构,居里温度与氮化温度相差不大.The structure and magnetic properties of the series of Sm2Fe17N2.9alloys prepared with the method of combination by means of X-ray Diffraction(XRD), A. C. initial susceptibility measurement,EBT measurement,TEM and SEM observation.The result of experiment indicates that, in the nitrogenation process, the magnetic property of Sm_2N is improved, as the temperature increased in the region . At 600 ℃, other main phase are decompounded. Curie temperature and nitrogenation temperature no distinction exists between.
