軸流コンプレッサーにおける固定ブレード及びジェットエンジンにおけるファンブレード;
シャトル及び接続用シャフトの如き繊維機械−製織機−における耐摩耗性の部分;
外科用インプラント、骨板、ジョイント;
耐摩耗性を改良し且つ擦過を回避するために表面機関における被覆層として用いた硬質表面仕上げ及び表面合金;
時計のケース;
化学工業及び石油工業用のポンプケース及び羽根車に適当である。
本発明によるハイポ共融Ti−6Si−2Al合金を、非消耗型のタングステン電極を用いてアーク溶融により製造した。99.8重量%より高い純度をもつチタンスポンジと、冶金品位の珪素と99.8重量%より高い純度のアルミニウム顆粒とを原料として用いた。合金は水冷式の銅製炉床上で薄い固体のスカル(skull)を形成することにより銅製炉床でのアーク溶融中は保持され、次いで銅製の型に注型してロッド様のインゴットを得た。これらのインゴットを回避及び研削により機械加工して平滑な表面仕上げを示す円筒状の圧縮及び引張り試験試料とした。
0.07重量%のYを添加しながらハイポ共融(近共融:near eutectic)の酸化物分散物で強化したTi−7Si−2Al合金を、実施例1に記載したアーク溶融技術により製造した。金属イットリウムを溶融物に添加し、約1200ppmの溶存酸素でY2O3を形成した。ブリネル硬度は347±2 HB 187.5/2.5であると測定した。測定した降伏強度は約960〜990 MPaである。ε=10−7s−1のクリープ速度で600℃での第1のクリープ実験では235〜255 MPaのクリープ強度を示した。
ハイポ共融の酸化物分散物で強化したTi−5.5 Si−3.5 Al−1.5 Cr−0.1Y合金を実施例1に記載した溶融方法の技術により製造した。金属イットリウムを溶融物に添加し、溶融物に溶存した酸素でY2O3を形成した。
