Abstract

The glass-forming ability and magnetic properties of (Fe, Co)-B-Si-Nb glassy alloys have been investigated. The maximum diameter for the formation of a glassy alloy rod was 2.0 mm for Fe72 B20 Si4 Nb4 and 4.0 mm for (Fe0.5 Co0.5) 72 B20 Si4 Nb4. A number of local-ordered regions are recognized in Fe72 B20 Si4 Nb4 bulk glassy alloy by high-resolution transmission electron microscopy. However, no local-ordered regions are observed in (Fe0.5 Co0.5) 72 B20 Si4 Nb4 bulk glassy alloy. Saturation magnetization, coercive force, and maximum permeability were 1.14 T, 1.5 Am, and 32 000, respectively, for the (Fe0.6 Co0.4) 72 B20 Si4 Nb4 bulk glassy alloy.
