Description
以下、実施例で更に詳細を説明する。
25種類のFe粉末は、水アトマイズFe粉であるため、酸素を不純物として多量(質量%で0.17〜0.2%の範囲)に含んでいる。酸化皮膜形成の寄与が大である。不純物Cの濃度は0.001〜0.003%程度である。またN濃度は、いずれの材料でも0.002%以下となり、非常に少ない。C,Nはアトマイズ中に水(すなわち酸素)との反応でかなりの量が除去されていると思われる。
温度範囲で等時焼鈍実験を実施した。焼鈍条件は、100℃からスタートして、温度上昇間隔ΔT=50℃,保持時間30分である。100,200,300,400,450,500,550,600,650,700,800までそれぞれ焼鈍した。焼鈍された成形体を上記のプロセスに従い、室温で硬さ試験した。
径15mm,厚さ5mmのリング形状とした。鉄リン酸ガラスの耐熱温度が最大550℃であ
るため、成形体を窒素ガス雰囲気で530℃で60分間の熱処理を行った。
