Abstract
Description
第3世代の単結晶合金ではレニウムを5〜6%添加することにより、第2世代の単結晶に対して高強度化を図ることができた。しかしながら、その反面、長時間の使用によりクリープおよび低サイクル破壊の起点となるTCP相が生成しやすい。この点から第3世代の単結晶超合金を大型ガスタービンに適用するのは困難であり、燃焼温度の上昇にともなうよりクリープ強度の高い材料の実現という要望に応えられない。
このように溶体化処理および時効処理を施した試料についてクリープ強度を測定した。クリープ試験では、温度900℃、応力392MPaと温度1000℃、応力245MPaおよび温度1100℃、応力137MPaの3条件で試料がクリープ破断するまでの時間を寿命とした。破断後の金属組織にTCPの析出は観察されなかった。
