讨论了快淬法制备的(Fe0.85B0.15)(100-x)Cux合金退火后的铜含量对磁性能的影响。在x=1.0~1.5范围内，随着x的增加，H-c值显著减小，晶粒度显著减小。当x=1.5时，合金表现出良好的磁性能，小的H-c约为7A/m，高的B，大于1.8T。在本合金体系中，添加1.0%以上的铜有利于纳米晶的形成和软磁性能的改善。
The Cu content dependence of magnetic properties in annealed (Fe0.85B0.15)(100-x)Cu-x alloys fabricated by melt-spinning was discussed. The value of H-c markedly decreases with increasing x between x = 1.0 and 1.5, accompanied with significant reduction of crystalline grain size. The alloy with x = 1.5 showed excellent magnetic properties such as a small H-c of about 7 A/m and a high B, of more than 1.8 T. For the present alloy system, more than 1.0% addition of Cu is effective for the formation of nano-scale grains and for the improvement of the soft magnetic properties.
