Abstract

Applying the hypercooling technique, the metastable-phase Fe3B, instead of the stable-phase Fe2B, is formed directly in the bulk Fe-B eutectic alloy melt and can be further preserved at room temperature. Measurement of magnetic properties shows that, for the bulk Fe-B eutectic alloy with Fe3B phase, the intrinsic coercivity and retentivity become smaller, and the saturation magnetization is larger, than the stable eutectic alloy (α-Fe/Fe2B) and some Fe-B amorphous alloys.
