Nanocrystalline Fe_(83)P_(16)Cu_1 soft magnetic alloy produced by crystallization of its amorphous precursor

摘要

A new Fe-based amorphous soft magnetic alloy with the nominal composition of Fe_(83)P_(16)Cu_1 was pro duced by melt-spinning technology. After annealed at 563 K for 120 s, the alloy consists of nanosized grains embedded in amorphous matrix. The nanocrystalline soft magnetic alloy shows good soft mag netic properties such as high saturation magnetic flux density 1.65 T and low coercivity 8.7 A/m. The sim ple composition together with low crystallization temperature and short annealing time make this soft magnetic alloy a promising candidate for industry use.
