| description | Provided is a Ni-based alloy having a composition consisting of, by mass%, Cr: 14.0% to 17.0% (preferably, not less than 14.0% and less than 15.0%), Fe: 5.0% to 9.0%, Ti: 2.2% to 2.8%, Al: 0.40% to 1.00%, a total amount of Nb + Ta: 0.7% to 1.2%, B: 0.001% to 0.010%, Zr: 0.01% to 0.15%, Mg: 0.001% to 0.050%, Mn: 0.01% to 0.20%, Cu: 0.005% to 0.300%, Mo: 0.01% to 0.30%, C: 0.01% to 0.05%, and the balance of Ni with inevitable impurities. In a creep test under conditions of a test temperature of 750°C and a test load of 330 MPa, the Ni-based alloy preferably has a creep rupture life of not less than 120 hours and an elongation of not less than 16%, i.e., has good high-temperature creep characteristics. The Ni-based alloy is suitable for a gas turbine member. |
