MAGNET PRODUCTION

A process is provided for the production of rare earth magnets comprising the steps of exposing a rare earth alloy to hydrogen gas at an elevated temperature so as to effect hydrogenation and disproportionation of the alloy, mechanically processing the disproportionated alloy, and degassing the processed alloy so as to effect hydrogen desorption and recombination of the alloy. The process of the invention finds use in the production and shaping of rare earth magnets, and may be particularly applicable to the production of thin magnetic sheets. 提供了用于制备稀土磁体的方法，所述方法包括以下步骤：将稀土合金在高温下暴露于氢气以实现所述合金的氢化和歧化，机械加工歧化的合金，并且使所述加工的合金脱气以实现所述合金的氢脱附和重组。本发明的方法可用于稀土磁体的制备和成形，并且可以特别地适用于薄磁片的制备。
