<p>A method for producing a quenched R-T-B-C alloy magnet, wherein R represents at least one element selected from the group consisting of rare earth elements and yttrium, T represents a transition element component having iron as a primary ingredient, B represents boron and C represents carbon, which comprises providing a R-T-B bonded magnet containing a resin or a R-T-B sintered magnet having a resin coating formed on the surface thereof, providing a solvent alloy containing the rare earth element R and the transition metal element T, and melting the R-T-B bonded magnet together with the solvent alloy. The method allows the recovery of a rare earth alloy from a used bonded magnet and a failed product generated in a production process step and the production of a quenched alloy magnet by the use of such a rare earth alloy, which leads to the recycling of a magnet having a resin component.</p> |
