  • Mô tả: The increase in Cu content from 1.0 to 1.7 at.% changes the as-spun Fe 86-x Si 2 B 8 P 4 Cu x and Fe 84-y Mn 2 Si 2 B 8 P 4 Cu y alloys from a single amorphous phase to a composite of α-Fe nanoparticles dispersing in amorphous matrix and significantly refines the nanostructure and improves the magnetic softness of the annealed alloys. The as-spun Fe 82.3 Mn 2 Si 2 B 8 P 4 Cu 1.7 amorphous alloy containing high number density α-Fe nanoparticles forms uniform nanostructure with fine α-Fe grains in an average size of 17 nm after annealing and exhibits low coercivity of 8.4 A m −1 and high effective permeability of 15000 at 1 kHz, which are superior to those of 38 nm, 85.4 A m −1 and 1400, respectively, for the Fe 83 Mn 2 Si 2 B 8 P 4 Cu 1 amorphous alloy. The mechanism relating to the effect of Cu content on the grain refinement was discussed in terms of the as-spun structure and crystallization process of the alloys.
