In a method for making a wrought nickel-chromium-molybdenum alloy having homogeneous, two-phase microstructures the alloy in ingot form is subjected to a homogenization treatment at a temperature between 2025&#xb0; F. and 2100&#xb0; F., and then hot worked at start temperature between 2025&#xb0; F. and 2100&#xb0; F. The alloy preferably contains 18.47 to 20.78 wt. % chromium, 19.24 to 20.87 wt. % molybdenum, 0.08 to 0.62 wt. % aluminum, less than 0.76 wt. % manganese, less than 2.10 wt. % iron, less than 0.56 wt. % copper, less than 0.14 wt. % silicon, up to 0.17 wt. % titanium, less than 0.013 wt. % carbon, and the balance nickel.
