ANISOTROPIC HIGH COERCIVE FORCE MAGNET, METHOD FOR PRODUCING ANISOTROPIC HIGH COERCIVE FORCE MAGNET, AND APPARATUS FOR PRODUCING ANISOTROPIC HIGH COERCIVE FORCE MAGNET

摘要

PROBLEM TO BE SOLVED: To solve such a problem that it is required much time, cost or the like for producing a magnet having high anisotropy and coercive force in the conventional high speed rapid cooling method and powder combustion method.;SOLUTION: The method for producing the anisotropic high coercive force magnet comprises: a float melting-holding step where a master alloy is floated in a melted state and is held; a free falling step where the floating state of the master alloy is released, and the master alloy is freely made to fall; and a step where the freely-fallen master alloy is held by plates clapping the same, and is compressed at a high strain rate.;COPYRIGHT: (C)2011,JPO&INPIT
