Description
-合金の組成に組み込まれる主な元素は、999~999.9パーミルの純度を有し、脱酸素されている。
-合金の組成元素を、ルツボに入れ、元素が溶融するまで加熱する。
-加熱は、アルゴン分圧下の密閉誘導炉内で実施する。
-溶融合金を、インゴット鋳型に鋳込む。
-固化後、インゴットを、任意選択で水焼入れ処理する。
-冷却されたインゴットを、次いで、冷間圧延し、その後焼きなましする。各焼きなましと焼きなましとの間の冷間加工の度合いは、40~80%である。
-各焼きなましは20~120分間持続し、純H2又はH2とN2との混合物からなる還元雰囲気下にて900℃~1100℃で実施する。
-焼きなまし作業後の冷却は、水焼入れ又は開放空気冷却により実施する。
