| 简介 |
The present invention provides a method of production of a rare earth magnet which achieves high magnetization by hot working and at the same time secures high coercivity.
A method of production of the present invention is a method for producing an R-T-B-based rare earth magnet comprising : molding a powder of an R-T-B-based rare earth alloy (R : rare earth element, T : Fe or Fe part of which is substituted by Co) to form a bulk; then hot working the bulk; and before the molding, mixing with the powder of an R-T-B-based rare earth alloy either a metal which forms a liquid phase in copresence with R at a temperature lower than the hot working temperature, or an alloy which forms a liquid phase at a temperature lower than the hot working temperature. |
