Abstract
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 Fe73.5Cu1Nb3Si13.5B9 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 Fe73.5Cu1Nb3Si13.5B9 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.
