摘要：
An alloy material having high-temperature corrosion resistance, which exhibits excellent oxidation resistance and ductility and can be applied to gas turbines used at ultra high temperatures, and a thermal barrier coating, a turbine member and a gas turbine each comprising the alloy material. An alloy material having high-temperature corrosion resistance, comprising, by weight, Co: 15 to 30%, Cr: 10 to 30%, Al: 4 to 15%, Y: 0.1 to 3%, and Re: 0.1 to 1%, with the balance being substantially Ni. Also, an alloy material having high-temperature corrosion resistance, comprising, by weight, Ni: 20 to 40%, Cr: 10 to 30%, Al: 4 to 15%, Y: 0.1 to 3%, and Re: 0.1 to 5%, with the balance being substantially Co.
