An improved nickel-based superalloy having high corrosion and oxidation resistance and good compatibility with a thermal barrier coating. The enhanced oxidation resistance and compatibility with the thermal barrier coating results from the inclusion of two or more rare earth elements. The superalloy is useful for the fabrication of components for a gas turbine.
