Nickel-base superalloy excellent in the oxidation resistance |
摘要 |
A nickel-base superalloy having excellent oxidation resistance is provided. It is useful as high-temperature members such as turbine blades and turbine vanes for jet engines or gas turbines. The nickel-base superalloy has a composition containing Co: 0.1 to 15% by weight, Cr: 0.1 to 10% by weight, Mo: 0.1 to 4.5% by weight, W: 0.1 to 15% by weight, Al: 2 to 8% by weight, Ta+Nb+Ti: 0 to 16% by weight, Hf: 0 to 5% by weight, Re: 0.1 to 16% by weight, Ru: 0.1 to 16% by weight, Si: 0.2 to 5% by weight and a balance made of Ni and unavoidable impurities. |
