Long-term creep behaviour of cast TiAl-Ta alloy
10.1016/j.intermet.2018.01.013 2018-01-20 The long-term creep behaviour of the cast Ti-44.4Al-8.1Ta (at.%) alloy with an initial γ-TiAl(L10)+α2-Ti3Al(D019) microstructure was investigated at 700 °C. The alloy shows a remarkable creep resistance. The minimum creep rate is measured to be as low as 1.47... |
