Abstract

Crystallization kinetics of a Fe83.3Si4.2B 12.5 amorphous alloy and a Fe83.3Si4B 8P4Cu0.7 hetero-amorphous alloy under magnetic fields was investigated by the differential thermal analysis (DTA). In DTA for Fe83.3Si4.2B12.5, the first crystallization peak, which indicates the precipitation of bcc-Fe shifts about 10 K toward the lower temperature side, whereas the second peak which indicates the precipitation of iron-compounds, shifts about 4 K toward the higher temperature side by applying a magnetic field of B = 20 T. On the other hand, in the case of Fe83.3Si4B8P4Cu0.7, the first peak at B = 20 T does not change in comparison with that at a zero magnetic field, whereas the second peak shifts toward a higher temperature side as well as Fe83.3Si4.2B12.5.
