Claim:
1. A process comprising: heating a nickel-base alloy workpiece in a first heating operation to a temperature greater than a M working the nickel-base alloy workpiece in a first working operation to a reduction in area of 20% to 70%, based on a cross-sectional area of the workpiece immediately prior to the first working operation, wherein the nickel-base alloy workpiece is at a temperature greater than a M heating the nickel-base alloy workpiece in a second heating operation to a temperature in a range of 1700° F. to less than the M working the nickel-base alloy workpiece in a second working operation to a second reduction in area of 20% to 70%, based on a cross-sectional area of the workpiece immediately prior to the second working operation, wherein the nickel-base alloy workpiece is at a temperature greater than 1700° F. and less than the M wherein the nickel-base alloy workpiece comprises, by weight, up to 0.05% carbon, 27.0% to 31.0% chromium, up to 0.5% copper, 7.0% to 11.0% iron, up to 0.5% manganese, up to 0.015% sulfur, up to 0.5% silicon, at least 58% nickel, and incidental impurities.
