<p>A process comprising: a first heating step comprising heating a nickel-base alloy 5 workpiece to a temperature greater than a M2 3C6 carbide solvus temperature of the nickel-base alloy; a first working step comprising working the heated nickel-base alloy workpiece to a reduction in area of 20% to 70%, wherein the nickel-base alloy workpiece is at a temperature greater than a M2 3 C6 carbide solvus temperature when the first working step begins; a second heating step comprising heating the 10 worked nickel-base alloy workpiece to a temperature in a range of 927*C (1700 0 F) to less than the M 23 C6 carbide solvus temperature of the nickel-base alloy, wherein the as-worked nickel-base alloy workpiece is maintained at elevated temperature and not permitted to cool to ambient temperature between completion of the first working step and beginning of the second heating step; and a second working step 15 conprising working the heated nickel-base alloy workpiece to a second reduction in area of 20% to 70%, wherein the nickel-base alloy workpiece is at a temperature greater than 927CC (1700 0 F) and less than the M2 3C6 carbide solvus temperature of the nickel-base alloy when the second working step begins.
