Curie Temperature of Amorphous Fe-Si-B and Fe-Si-B Alloys

摘要

The effects of composition, annealing temperature and time, annealing heating rate on the Curie temperature of amorphous Fe-Si-B and Fe-W- Si-B alloy were studied. The results indicate that the Curie temperature of these alloys increases with the increase of the metalloid content when it is <25 At/100, then decreases with the further increase f the metalloid content. For amorphous Fe-Si-B and Fe- W-Si-B alloys with the low methalloid content, the Curie temperature increases with the annealing temper- ature an the annealing time.
