摘要：

The creep response of a nearly-lamellar Ti-45Al-10Nb at 760 degreesC 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 x 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. (C) 2001 Elsevier Science B.V. All rights reserved.
