Abstract
Description
析出硬化型Ni合金粉末を用いて金属粉末射出成形法により焼結体を成形した。焼結体については、金属組織観察用及び疲労試験用に各々成形した。析出硬化型Ni合金粉末には、Alloy718(登録商標)粉末を使用した。析出硬化型Ni合金粉末の合金組成については、20.40質量%のCrと、16.40質量%Feと、3.10質量%のMoと、5.20質量%のNbと、1.00質量%のTiと、0.50質量%のAlと、を含み、残部がNiと、0.05質量%のC等の不可避的不純物とにより構成されている。析出硬化型Ni合金粉末には、平均粒径が35μmよりも小さいガスアトマイズ粉末を用いた。
金属粉末射出成形法で成形した焼結体を、各熱処理条件で熱処理して実施例1から4、比較例1の試験片を作製した。なお、焼結体については、いずれの試験片も同じ成形条件で作製したものを使用した。
次に、各熱処理後の試験片について、金属組織観察を行った。なお、金属組織観察については、試験片を埋込樹脂に埋め込んだ後に研磨とエッチィングとを行って、光学顕微鏡により観察した。図3Aは、比較例1の試験片の金属組織観察結果を示す写真であり、図3Bは、実施例1の試験片の金属組織観察結果を示す写真であり、図3Cは、実施例2の試験片の金属組織観察結果を示す写真であり、図3Dは、実施例3の試験片の金属組織観察結果を示す写真であり、図3Eは、実施例4の試験片の金属組織観察結果を示す写真である。
疲労試験については、ASTM E466に準拠して室温と高温とにより行った。室温疲労試験については、応力比R=-1(両振り応力)、応力振幅400MPaから600MPaとした。高温疲労試験については、試験温度538℃、応力比R=-1(両振り応力)、応力振幅500MPaから600MPaとした。なお、室温疲労試験については、比較例1及び実施例2の試験片について実施し、高温疲労試験については、実施例1及び実施例2の試験片について実施した。なお、サイクル数が1×107回で疲労破壊しないものについては、その時点で試験を中止した。
