Fe:81.0at%、Nb:7.0at%、P:3.0at%、B:9.0at%の組成の母合金が得られるように各種原料金属等をそれぞれ秤量した。そして、チャンバー内で真空引きした後、高周波加熱にて溶解し母合金を作製した。
実験例2では、母合金の組成を表2に記載の組成(上記組成(2)または上記組成(2)に近い組成)に変化させた。そして、表1の試料番号16と同条件で熱処理を行った。具体的には、セッターの材質をカーボンとし、1回目の熱処理温度を450℃、1回目の熱処理時間を1時間、2回目の熱処理温度を650℃、2回目の熱処理時間を1時間とした。
実験例3では、母合金の組成を表4に記載の組成(上記組成(3)または上記組成(3)に近い組成)に変化させた。そして、表1の試料番号16と同条件で熱処理を行った。具体的には、セッターの材質をカーボンとし、1回目の熱処理温度を450℃、1回目の熱処理時間を1時間、2回目の熱処理温度を650℃、2回目の熱処理時間を1時間とした。
実験例4では、母合金の組成を表6に記載の組成(上記組成(4)または上記組成(4)に近い組成)に変化させた。そして、表1の試料番号16と同条件で熱処理を行った。具体的には、セッターの材質をカーボンとし、1回目の熱処理温度を450℃、1回目の熱処理時間を1時間、2回目の熱処理温度を650℃、2回目の熱処理時間を1時間とした。
実験例5では、試料番号16のFeの一部をX1に置換した点以外は実験例2と同条件で実施し、評価した。X線回折測定の結果、全ての実施例は非晶質であった。そして、全ての実施例でFe−poor相およびFe−rich相が存在した。結果を表8に示す。
