Patent ID: 7531054

Claim:
A method of processing a nickel-base alloy comprising, in percent by weight, up to about 0.1% carbon, from about 12% to about 20% chromium, up to about 4% molybdenum, up to about 6% tungsten, from about 5% to about 12% cobalt, up to about 14% iron, from about 4% to about 8% niobium, from about 0.6% to about 2.6% aluminum, from about 0.4% to about 1.4% titanium, from about 0.003% to about 0.03% phosphorus, from about 0.003% to about 0.015% boron, and nickel; wherein a sum of the weight percent of molybdenum and the weight percent of tungsten is at least about 2% and not more than about 8%, and wherein a sum of atomic percent aluminum and atomic percent titanium is from about 2% to about 6%, a ratio of atomic percent aluminum to atomic percent titanium is at least about 1.5, and the sum of atomic percent aluminum and atomic percent titanium divided by atomic percent niobium is from about 0.8 to about 1.3, the method comprising: working said nickel-base alloy into a desired shape; and direct aging said nickel-base alloy.
