采用熔融纺丝法制备了主要含Ce2Fe14B相的Ce12+xFe82-xB6 （x=0、0.5、1、1.5、2、3）磁性材料。Ce12Fe81B6带的矫顽力最低。随着Ce含量的增加，矫顽力单调增加，x射线技术表明，次要相Fe3B的数量减少，而CeFe2的数量增加。磁化反转和磁性能取决于小相的数量。Ce13.5Fe80.5B6带的磁滞回线平整度最高，能量积为6.80 MGOe。为了平衡利用稀土资源，优化相构成是提高铈基合金磁性能的必要条件。(C) 2016 Elsevier B.V.版权所有
Magnetic materials of Ce12+xFe82-xB6 (x=0, 0.5, 1, 1.5, 2, and 3) containing mainly Ce2Fe14B phase were prepared by melt spinning method. The coercivity is the lowest in Ce12Fe81B6 ribbons. With the increase of Ce content, the coercivity increases monotonically, and X-ray techniques show that the amount of minor phase Fe3B decreases but the amount of CeFe2 increases. Magnetization reversal and magnetic properties are dependent on the amount of minor phases. The squareness of hysteresis loop is the best in Ce13.5Fe80.5B6 ribbons with energy product of 6.80 MGOe. Optimizing the phase constitution is necessary to improve magnetic properties in Ce-based alloys for utilizing the rare earth resource in a balanced manner. (C) 2016 Elsevier B.V. All rights reserved.
