| titleOfInvention | Rare earth magnet manufacturing method |
| abstract | The present invention provides a method for producing a rare earth magnet by increasing the density of a compact formed from a metal powder containing a rare earth element and suppressing a decrease in residual magnetic flux density of the rare earth magnet accompanying an increase in the density of the compact. . A rare earth magnet manufacturing method includes a powder preparation step of preparing a metal powder from a raw material alloy containing a rare earth element, a molding step of supplying the metal powder into a mold to form a molded body, An orientation process for applying a magnetic field to the held compact to orient the metal powder contained in the compact and a sintering process for sintering the compact, and the stress relaxation rate of the metal powder is 7%. It is 35% or less. [Selection] Figure 3 |
