A method for preparing a rare earth permanent magnet improved performance rare earth permanent magnet material, and

The present application discloses a method and a rare earth permanent magnet material prepared rare earth permanent magnet material in combination. The method comprising: after the step of pressing the blank, and before the isostatic pressing step, the blank is arranged perpendicular to the pressed surface in the direction of orientation of the magnetic field source powder of a rare earth, provided that the weight percentage of rare earth powder heavy rare earth element source not less than the weight percent other rare earth elements. Since the products of the invention the step of adding rare earth element after pressing the blank, it can be prepared in various shapes and sizes, which process is simple, Hcj is improved without changing the conventional routing premise, and uniform distribution Hcj .
