PROBLEM TO BE SOLVED: To provide an Ni-base casting alloy which is cast by an ordinary process and is superior in corrosion resistance and oxidation resistance, and also has high strength, and to provide a high-temperature member for a gas turbine superior in durability. SOLUTION: The nickel-base alloy includes, by mass%, 15.1-18.0% Cr, 1.0-7.9% Co, 2.6-3.4% Al, 4.1-5.6% Ti, 2.0-4.0% Ta, 3.5-4.9% W, 0.1-1.9% Mo, 0.05-0.20% C, 0.01-0.03% B and the balance Ni with unavoidable impurities. The high-temperature member for the gas turbine is manufactured by using the same. COPYRIGHT: (C)2011,JPO&INPIT |
