Abstract
A method for heat treating a nickel base alloy includes the steps of: a. heating a nickel base alloy to at least its delta (δ) phase solvus temperature, and lower than its incipient melting temperature for a predetermined time sufficient to dissolve substantially all of the nickel base alloy's delta (δ) phase, and b. cooling the nickel base alloy to a temperature below the gamma prime (υ) precipitation temperature at a rate sufficient to precipitate the alloy's chromium carbide and gamma prime (υ) in a serrated grain boundary.
