最丰富的稀土元素在永磁材料中的应用研究引起了人们的浓厚兴趣。然而，由于传统的Ce替代Nd，磁性能随着Ce含量的增加而急剧下降。采用双主相合金法调整磁体中主相的成分和组合，制作出部分不含Ce的主相，可以保持较高的剩磁。研究了Ce含量对双主相合金法烧结(Nd1-xCex)(30)(Fe,TM)(bal)B-1退磁曲线矩形性和磁性能的影响。当Ce含量为所有稀土金属总量的30%时，烧结磁体的最大磁能积仍超过43MGOe。
Research on the application of the most abundant rare-earth elements for permanent magnetic materials has gained intense interest. However, the magnetic properties decrease dramatically with the increase of Ce content due to the traditional Ce substitute for Nd. A double main phase alloy method has been performed to adjust the composition and combination of main phases in the magnets and make a partial main phase without Ce, which can maintain higher remanence. The influence of Ce content on the rectangularity of demagnetization curves and magnetic properties of (Nd1-xCex)(30)(Fe,TM)(bal) B-1 sintered by the double main phase alloy method has been investigated. When the Ce content was 30% of the total amounts of all the rare earth metals, the maximum energy product of the sintered magnet, was still over 43 MGOe.
