Abstract:
A method for creating an integrally bladed rotor comprising the steps of:providing a hub section formed from a metal alloy; welding an airfoil formed from a metal alloy to said hub section; partially aging at least one of said hub section and said airfoil at a temperature in the range of from about 1075Â° F. to about 1125Â° F. for a time period in the range of from about 2 hours to about 8 hours prior to said welding step; and aging said airfoil and a weld joint between said airfoil and said hub section subsequent to said welding step at a temperature in the range of 1275Â° F. to 1325Â° F. for a time period in the range of about 1 hour to about 4 hours.
