More Information
Summary:A nickel based alloy, along with methods of its use and manufacture, is provided that may include about 20 wt. % to about 26 wt. % cobalt; about 9 wt. % to about 13 wt. % chromium; about 2 wt. % to about 6 wt. % iron; about 3.5 wt. % to about 6 wt. % aluminum; about 9 wt. % to about 13 wt. % tungsten; about 6 wt. % to about 9 wt. % tantalum; about 0.06 wt. % to about 0.20 wt. % boron; and the balance nickel. The nickel based alloy may have gamma prime precipitates in a plurality of grain interiors and a gamma prime solvus temperature of about 1038° C. or greater. Additionally or alternatively, the nickel based alloy may comprise about 30% by volume or more gamma prime precipitates in the plurality of grain interiors.
