Abstract
The present disclosure provides a method for manufacturing a multi-main-phase structure magnet having excellent coercive force and a multi-main-phase structure magnet manufactured therefrom.
Claims18
A method for manufacturing a multi-main-phase structure magnet, the method comprising steps of:
- preparing a mixed powder by mixing a first powder having a composition of Re1—Fe—B and a second powder having a composition of Re2—Fe—B;
- and
- manufacturing the mixed powder into an anisotropic bulk magnet by performing anisotropic bulking of the mixed powder,
- wherein the rare earth metals included in Re1 are different from the rare earth metals included in Re2 in one or more of a type and a content of the metals.
