  • Abstract
    The glass-forming ability (GFA) and the magnetic properties of the (Fe0.80Co0.20)96-xBxSi1Nb3-yYy(x = 15, 17) amorphous alloys have been studied. It was confirmed that GFA is enhanced by replacing Nb with Y. Yttrium gives a complex effect on the magnetization. When Y content is increased, the saturation mass magnetization (σs) decreases first. However, the σs then increases and exhibits a maximum ~2 at% Y. The value of σs of the alloy with x = 17 and y = 2 in an as-quenched state is 211 × 10-6 Wb m/kg, which is slightly larger than that of the Y-free alloy with the same B content. The values of the coercivity of these alloys are less than 10 A/m in an as-quenched state. The coercivity shows a tendency to decrease with increasing Y content, which means the increase of GFA. These results indicate that the partial replacement of Nb by Y in the Fe-Co-B-Si-Nb alloys is useful to the simultaneous achievement of high GFA, high σs, and good soft magnetic properties.
