摘要： Nickel-base alloys with improved elevated temperature creep and stress rupture lives are disclosed which are particularly useful for components in gas turbine engines exposed to high temperatures and stresses for long periods of time. The alloys are nickel-based consisting essentially of 0.005 to 0.15% C, 0.10 to 11% Mo, 0.10 to 4.25% W, from 12 to 31% Cr, 0.25 to 21% Co, up to 5% Fe, 0.10 to 3.75% Nb, 0.10 to 1.25% Ta, 0.01 to 0.10% Zr, 0.10 to 0.50% Mn, 0.10 to 1% V, l.8-4.75% Ti, 0.5 to 5.25% Al, less than 0.003% P, and 0.004 to 0.025% B. Key to the improvement of creep and stress rupture lives is the extremely low P content in conjunction with high B contents.
