Abstract
A nickel base alloy includes: by mass, 0.001 to 0.1% of carbon; 12 to 23% of chromium; 15 to 25% of cobalt; 3.5 to 5.0% of aluminum; 4 to 12% of molybdenum; 0.1 to 7.0% of tungsten; and a total amount of Ti, Ta and Nb being not more than 0.5%. A parameter Ps represented by a formula (1) shown below is 0.6 to 1.6,Ps=−7×[C]−0.1×[Mo]+0.5×[Al] (1)where [C] indicates an amount of carbon; [Mo] indicates an amount of molybdenum; and [Al] indicates an amount of aluminum, by mass percent.
