Abstract
A soft magnetic bulky alloy according to the present invention is obtained by forming under pressure a powder and granule material mainly made of a Fe-M-B based amorphous alloy containing Fe, B and M where M is at least one element selected from a group consisting of Ti, Zr, Hf, V, Nb, Ta, Mo and W. In the soft magnetic bulky alloy, an amorphous alloy phase and a bcc phase with fine grain sizes of 30 nm or below are present in a mixed state, or the bcc phase with fine grain sizes of 30 nm or below is mainly present. The present invention also discloses a method of manufacturing such a soft magnetic bulky alloy.
