High-abundance rare earth element-containing magnet steel, its manufacturing method and application

Abstract

The present invention discloses a magnet steel containing high-abundance rare earth elements, a manufacturing method thereof, and applications thereof. [Solution] The main phase of the high-abundance rare earth element-containing magnet steel includes a main phase center, a main phase outer layer, and a main phase epitaxial layer, the main phase outer layer being located outside the main phase center and completely covering it, and the main phase epitaxial layer being located outside the main phase outer layer and completely covering it, wherein the content of the high-abundance rare earth element RE1 in the main phase center is A1 at %, the content of the high-abundance rare earth element RE2 in the main phase outer layer is A2 at %, A1 at % > A2 at %, the average diameter of the main phase center is r1, the average thickness of the main phase outer layer is r2, and
