Thermal stabilities of structure and soft magnetic properties were investigated for melt-spun Fe-Al-Ca-P-C-B-Si glassy alloy ribbon with various sample thicknesses. No change in structure and soft magnetic properties for Fe70Al6Ga1P11.4C4B4Si3.6 can be observed by holding at the starting temperature of endothermic reaction for glass transition (Tgonset) for 1.6 ks, which is much longer than those of conventional Fe-based amorphous alloys without supercooled liquid region. The thermal stability of Fe-based glassy alloy increases with increase of the width of supercooled liquid region. It does not, however, depend upon sample thickness. We can, therefore, hope that bulky Fe-Al-Ga-P-C-B-Si glassy alloy has a high workability without inferior of soft magnetic properties, because deformation and working processes are much easier in the supercooled liquid region owing to its low viscosity and ideal Newtonian flow.
