PROBLEM TO BE SOLVED: To provide an Ni-based normal casting alloy that is excellent in corrosion resistance and oxidation resistance and has high strength, and to provide a gas turbine that is excellent in durability. SOLUTION: The nickel base alloy comprises: 13.1-16.0 mass% Cr; 1.0-6.8 mass% Co; 3.0-3.4 mass% Al; 4.6-5.6 mass% Ti; 2.0-4.4 mass% Ta; 3.5-4.9 mass% W; 0.1-0.9 mass% Mo; 0.3-1.4 mass% Nb; 0.05-0.20 mass% C; 0.01-0.03 mass% B; and the balance Ni with inevitable impurities. A high temperature member for the gas turbine is formed of the alloy. COPYRIGHT: (C)2012,JPO&INPIT |
