Abstract (en)
[origin: US2013133793A1] A method for heat treating a 718-type nickel-base comprises heating a 718-type nickel-base alloy to a heat treating temperature, and holding the alloy at the heat treating temperature for a heat treating time sufficient to form an equilibrium or near-equilibrium concentration of delta-phase grain boundary precipitates within the nickel-base alloy and up to 25 percent by weight of total gamma'-phase and gamma''-phase. The 718-type nickel-base alloy is air cooled. The present disclosure also includes a 718-type nickel-base alloy comprising a near-equilibrium concentration of delta-phase grain boundary precipitates and up to 25 percent by weight of total gamma'-phase and gamma''-phase precipitates. Alloys according to the disclosure may be included in articles of manufacture such as, for example, face sheet, honeycomb core elements, and honeycomb panels for thermal protection systems for hypersonic flight vehicles and space vehicles.
