Description
第1実施形態:本実施形態では、本発明に係るNi基耐熱合金の基本組成である、Ni−Ir−Al−W合金について、Ru、Re添加の効果を確認した。2.0質量%のRu、3.0質量%のReを添加した合金を製造した。具体的には、Ni−Ir−Al−W合金(Ir:25.0質量%、Al:4.38質量%、W:14.33質量%、残部Ni)と、この合金に2.0質量%のRu、3.0質量%のReを添加したNi基耐熱合金を製造し、その機械的性質を評価した。また、Ni−Ir−Al−W合金にCo等の添加元素を添加したNi基耐熱合金の製造及び評価も行っている。
各試験片について、走査示差熱量測定(DSC)を行い、γ’相固溶温度(ソルバス温度)を測定した。測定条件は、測定温度範囲を〜1600℃として昇温速度10℃/minとした。そして、γ’相の分解・固溶によって発現する吸熱ピーク位置からγ’相固溶温度を測定した。
各試験片について、ビッカース試験(荷重500gf、加圧時間15秒)を行い硬度測定した。また、各試験片について圧縮試験を行って応力−ひずみ線図を作成し、これを基にして0.2%耐力を求めて圧縮強度を評価した。これらの硬度・強度測定は、常温(室温:25℃)と高温(900℃)で行った。
各試験片について高温曲げ試験を行い、合金の靭性(延性)を評価した。この試験では、900℃の高温雰囲気中で荷重を変化させつつ曲げ試験を行って荷重−変位線図を作成し、材料破断時の変位量を測定した。
