The process of crystallization from amorphous state in ribbons of Fe–Si–B–based alloys under the effect of a high DC magnetic field

详细

The effect of a high dc magnetic field (up to 29 T) applied during the crystallizing annealing of amorphous ribbons on the structure of Fe₈₁Si₇B₁₂ and Fe_73.5Cu₁Nb₃Si_13.5B₉ alloys has been studied. In the Fe₈₁Si₇B₁₂ alloy, an increase in the average size of grains that form during magnetic annealing has been revealed; in the Fe_73.5Cu₁Nb₃Si_13.5B₉ alloy, a small decrease is observed in the average grain size. The possible reason for this may be the differences in the specific features of the processes of crystallization of these alloys. No effect of the magnetic field on the crystallographic orientation of the arising grains has been revealed.
