Description
試料1及び2の各々について、以下に記載する化学組成(原子数比)を有するTiAl合金原料を用意し、これを高周波真空溶解炉にて溶解して鋳型に投入し、常温まで冷却して鋳造することによって、鍛造用のTiAl合金材の試料を調製した。尚、不可避不純物については、その含有量は少量であるので、以下においては記載を省略する。
試料2: Ti-44.7Al-3.7Nb-3.5V
圧縮試験の試験片として、上述の試料の調製において所定形状の鋳型を用いて、鋳型の形状に対応した鍛造用のTiAl合金材の試料(試料1~2)を作成した。各試料について、試験片を用いて以下の圧縮試験を行った。
実施例1と同様の調製方法に従って、試料1の鍛造用のTiAl合金材を調製した。尚、試料の調製において、鋳型を用いて所定形状に鍛造用のTiAl合金を成形した。
上述で得られた鍛造用のTiAl合金材を、アルゴンガスによる不活性雰囲気中で加熱して温度を1150~1175℃に保持し、歪速度:1/秒でプレス型鍛造して、製品のネットシェイプに加工した。この熱間鍛造による加工を繰り返したところ、図5の写真に示すように、鍛造割れを生じずに良好に加工を行うことができた。
