摘要
采用电场烧结法制备出纳米复相Nd10.5Dy0.5Fe76.9Nb1Co5B6.1永磁块体,研究了电场烧结温度对其磁性能和抗压强度的影响,采用XRD,SEM等方法分别对其相结构、显微组织进行了分析。结果表明:非晶合金压制成型后,经823K,300s电场烧结制得的纳米晶永磁块体具有最佳磁性能:Br=0.6498T,Hcj=714kA/m,(BH)max=63kJ/m3。随着烧结温度的升高,块体的抗压强度增加。
The permanent bulk magnets of Nd10.5Dy0.5Fe76.9Nb1Co5B6.1 were prepared by the process of field-activated sintering in this paper. The microstructure was discussed by XRD, SEM and so on. The results show that the optimal magnetic properties of Nd10.5Dy0.5Fe76.9Nb1Co5B6.1 （Br=0.6498 T, Hcj=714 kA/m, （BH）max=63 kJ/m^3） magnets have been obtained while treated at 823 K for 300 s by field-activated sintering. The compressive strength increases as the increase of sintedng temperature.
