Fe-B-C amorphous alloys with room-temperature saturation induction over 17.5 kG

Abstract
Amorphous alloys of Fe86B14−xCx (5⩽x⩽7) were found to have room‐temperature saturation induction approaching 18 kG after appropriate heat treatment. The alloys possess excellent soft‐magnetic properties with the ac loss less than 0.5 W/kg at 17 kG and 60 Hz. It is expected that the application of these alloys to power transformers will produce very large savings of energy.
