摘要：

This paper reports on the preparation of Fe;Si;B;P;C;soft magnetic amorphous alloys with a distinctly high Fe content of 93.5-95.5 wt.% by component design and composition adjustment. All alloys can be readily fabricated into completely amorphous ribbon samples with good surface quality by the single copper roller melt-spinning method. These alloys show good bending ductility and excellent magnetic properties after annealing, i.e., low coercivity（H;） of 3.3-5.9 A/m, high permeability（μ;）of 5000-10000 and high flux saturation density（B;） of 1.63-1.66 T. The mechanism of the good glass forming ability（GFA） and soft-magnetic properties are explored. The amorphous alloys with the high Fe content comparable to that of the desired high Si alloy can be promising candidates for the potential application in electric devices.
