Composite hard magnetic material and method for producing the same

摘要

The present invention provides a method for producing a composite hard magnetic material, wherein a composite powder - prepared by mixing; a composite hard magnetic material produced by consolidating a composite powder prepared by mixing an alloy powder having an amorphous phase containing a main component Co and at least Sm, and an alloy powder comprising an amorphous phase as a principal phase and containing at least Fe and/or Co, rare earth elements R and B; an alloy powder having an amorphous phase containing a main component Co and at least Sm; and an alloy powder having an amorphous phase containing at least Fe and/or Co, rare earth elements R and B - is consolidated by taking advantage of softening phenomenon caused by crystallization of the amorphous phase in the alloy powder comprising an amorphous phase as a principal phase. <IMAGE>
