Patent ID: 7653995

Claim:
A method for repairing a component formed of a superalloy material having the following nominal composition expressed as weight percentages: carbon 0.07%; chrome 8%; cobalt 9%; molybdenum 0.5%; tungsten 10%; tantalum 3.2%; titanium 0.7%; aluminum 5.6%; boron 0.015%; zirconium 0.01%; hafnium 1.4%; and the balance nickel, the method comprising: heating the component in a vacuum furnace to a soak temperature of 2,225° F.±25° F. at a rate sufficiently slow to avoid cracking of the component; allowing the material to soak at the soak temperature; cooling the component in the furnace at a rate of 1° F.±0.5° F. per minute to an intermediate temperature of 1,625±25° F.; gas fan quenching the component to a temperature of no more than about 300° F.; and performing a fusion repair weld on the component at an ambient temperature.
