摘要： A gamma prime nickel-based superalloy is provided, which can include a combination of Ti and Zr in a total weight amount sufficient to form cellular precipitates (30) located at grain boundaries (32) of the alloy, wherein the cellular precipitates (30) define gamma prime arms (42) that distort the grain boundaries (32) at which they are located. The Hf-containing, gamma prime nickel-based superalloy and/or the gamma prime nickel-based superalloy can include cellular precipitates (30) that are predominantly located at grain boundaries (32) of the alloy such that the cellular precipitates (30) define gamma prime arms (42) that distort the grain boundaries (32) at which they are located. The superalloys can further include finer gamma prime precipitates (e.g., cuboidal or spherical precipitates) than the cellular precipitates (30).

摘要： A gamma prime nickel-base superalloy and components formed therefrom that exhibit improved high-temperature dwell capabilities, including creep and hold time fatigue crack growth behavior. A particular example of a component is a powder metallurgy turbine disk of a gas turbine engine. The gamma-prime nickel-base superalloy contains, by weight: 16.0 to 30.0% cobalt; 9.5 to 12.5% chromium; 4.0 to 6.0% tantalum; 2.0 to 4.0% aluminum; 2.0 to 3.4% titanium; 3.0 to 6.0% tungsten; 1.0 to 4.0% molybdenum; 1.5 to 3.5% niobium; up to 1.0% hafnium; 0.02 to 0.20% carbon; 0.01 to 0.05% boron; 0.02 to 0.10% zirconium; the balance essentially nickel and impurities. The superalloy has a W+Nb-Cr value of at least -6, is free of observable amounts of sigma and eta phases, and exhibits a time to 0.2% creep at 1300°F and 100 ksi of at least 1000 hours.
