概要
- 論文の詳細を見る
The hard magnetic material with a maximum _iH_c of about 30 kOe was obtained by crystallizing Nd-Fe-B alloys from the amorphous phase. The hard magnetic properties are considered to be due to single domain behaviors of the Nd_2Fe_<14>B fine grains, which are precipitated by annealing at 600-800℃ for less than 3 min. When the specimens are further crystallized, Nd_2Fe_<17> or α-Fe appears at the expense of the region of Nd_2Fe_<14>B phase.
