Process for manufacturing articles and alloys made from high-temperature, high-damage superalloys, superalloys

摘要

Lt; RTI ID = 0.0 weight percent / RTI About 3 to about 9 W, a maximum of about 8, a maximum of Co of about 12, an Al of about 1 to about 3, a Ti of about 0.6 to about 10, a Cr of about 0.005 to about 0.06, a Cr of about 13 to about 17, 3, Nb up to about 5.5, B about 0.001 to about 0.012, Mg about 0.0010 to about 0.0020, Zr about 0.01 to about 0.08, Si up to about 0.7, P up to about 0.05, the remainder nickel, conventional impurities, / RTI as a remainder. This alloy provides a combination of high strength, good creep resistance and good crack growth resistance. A method of heat treating a nickel-based superalloy to improve tensile ductility of the alloy is also disclosed. An article of manufacture made from the nickel-based superalloy described herein is also disclosed.
