| 简介 |
The present invention includes a step in which a green compact formed by compacting a magnet powder for constituting an R-Fe-B based sintered magnet having Nd as the principal component and containing a rare earth element R is molded by press-molding the magnet powder; a sintering step in which the green compact is sintered under the condition of being heated to the sintering temperature, molding a sintered magnet; a dimension correction step in which the sintered magnet is pressure molded under the condition of being heated to a temperature not exceeding the sintering temperature, thereby correcting the dimensions of the sintered magnet; and an aging heat treatment step utilizing the heated atmosphere produced in the dimension correction step, and in which the texture of the sintered magnet is adjusted. |
