摘要：
The effect of 1 at.% Cu addition and annealing temperatures on the soft magnetic properties of Fe81B13P3Si2C1 amorphous ribbons was investigated in this paper. The results show that both Fe81B13P3Si2C1 and (Fe81B13P3Si2C1)(0.99)Cu-1 amorphous/nanocrystalline alloys possess excellent soft magnetic properties. Minor Cu addition can enlarge the temperature interval between first and second crystalline temperatures from 48 K to 112 K, enlarging the processing window and increasing the thermal stability of the amorphous alloy. The annealed Fe81B13P3Si2C1 amorphous/nanocrystalline alloy exhibits saturation flux densities (B-s) on the order of 1.69 T and coercivities (H-c) of 14.6 A/m, and the annealed (Fe81B13P3Si2C1)(0.99)Cu-1 alloy shows a high B-s value of up to 1.92 T and H-c of 11.6 A/m. The soft magnetic properties were discussed in terms of microstructure and magnetic domain observation. (c) 2020 Author(s).
