摘要：
In this study, we investigated an Fe-B-P-Cu system nanocrystalline alloy with both high saturation magnetic flux density and low coercivity. In particular, we manufactured as-quenched Fe84.3B6P9Cu0.7 alloy powder with a smooth and spherical surface. After annealing, this powder showed a nanocrystalline structure, low coercivity, and saturation magnetic flux density of 1.68 T. These magnetic properties are excellent compared to those of conventional powders. Thus, Fe84.3B6P9Cu0.7 nanocrystalline alloy powder can be used to produce superior inductors with high saturation magnetic flux density as well as low coercivity.
