Abstract

The creep response of a nearly-lamellar Ti-45Al-10Nb at 760°C and 207 MPa suggests that high Nb additions greatly improve the creep resistance of TiAl alloys. The alloy exhibited a minimum creep rate of 6 × 10^-9 s^-1 and the time to 0.5% strain of 80 h. These properties are comparable to that of the most creep resistant wrought and cast TiAl-base alloys.
