<p><P>PROBLEM TO BE SOLVED: To provide a method of producing an anisotropic permanent magnet of nanocrystal in which the coercive force and the remanent magnetic flux density are controlled according to the parts. <P>SOLUTION: In the method of producing an anisotropic permanent magnet by upsetting processing of a nanocrystal magnet material, the upsetting processing is performed by setting the friction coefficient of a die for the upsetting processing and the nanocrystal magnet material relatively high in the low distortion introduction scheduled part of the nanocrystal magnet material, and setting the friction coefficient relatively low in the high distortion introduction scheduled part of the nanocrystal magnet material. Desirably, the relatively high friction coefficient is 0.4 or more, and the relatively low friction coefficient is 0.1 or less. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
