摘要:
研究了不同含量的Nb添加对(Nd0.5Ce0.5)13Fe82-xNbxB5快淬合金的磁性能、物相组成、交换耦合作用及其初始磁化机制的影响.发现Nb添加能抑制α-Fe的形成,显著改善合金的磁性能. 当Nb的添加量(原子分数)为0.5% 时,合金获得较优的磁性能.随着Nb的添加量(原子分数)从0增加到0.5%,合金的矫顽力由未添加时的777 kA/m提升到900 kA/m,最大磁能积也从未添加Nb时的64 kJ/m3增加到78 kJ/m3,而合金的剩磁仅由未添加Nb时的0.71 T轻微下降到0.70 T.合金中晶粒间的交换耦合作用随着Nb的添加而增强.合金的初始磁化机制也有了显著地变化.
