摘　　要：Using melt spinning technology,we successfully synthesized a series of Fe-rich Fe–P–C amorphous alloys exhibiting high saturation magnetization(B_(s)),low coercivity(H_(c)),and excellent bending ductility.These alloys exhibit low H_(c)values ranging from 4.1 to 7.2 A/m,and high B_(s)values ranging from 1.58 to 1.68 T.Particularly,after annealing at 588 K for 900 s,the Fe_(83)P_(11)C_(6)amorphous alloy showed extraordinary soft magnetic properties:B_(s)up to 1.68 T,H_(c)only 4.7 A/m,and the core loss at approximately 1.5 W/kg under the condition of 0.5 T and 50Hz,all of which surpass the reported Fe–P–C ternary amorphous and nanocrystalline alloys.These Fe-rich Fe–P–C alloy ribbon samples exhibit favorable bending ductility in both the as-spun and annealed states.Their simple alloy composition,outstanding soft magnetic properties,and excellent flexibility collectively make these soft magnetic alloys highly promising candidate materials for industrial applications.
