[231] Relationship between hydrogen pressure and temperature for recombination reaction in the HDDR process of Ce-Fe-B alloy

*Ryo SHIMBO1,2, Takashi HORIKAWA1,2, Masao YAMAZAKI2, Masashi MATSUURA1, Ryosuke KAINUMA1, Satoshi SUGIMOTO1 (1. Tohoku Univ., 2. Aichi Steel Corp.)

Keywords:Ce-Fe-B、HDDR、希土類磁石粉末、再結合反応

Ce-Fe-B系合金に存在するCe2Fe14B相とCeFe2相のHDDR反応における水素圧力と温度の関係を調査した結果,Ce2Fe14B相はNd2Fe14B相よりも再結合しやすく,CeFe2相はそれらよりも再結合しにくいことが分かった.
