Abstract :
The fabrication of Fe-based soft magnetic amorphous cores by powder metallurgical process using various consolidation techniques is discussed. In this study, FeSiB amorphous powder cores with an addition of permalloy powder were prepared by cold pressing. The effects of the permalloy powder on the high-frequency magnetic properties such as permeability, coercivity and eddy current loss were reported. According to the cross-sectional SEM micrograph of the compacted core, the permalloy powders were plastically deformed by cold pressing and this can be helpful for compaction of amorphous powder cores.
