20110198001METHOD OF HEAT TREATING A SUPERALLOY COMPONENT AND AN ALLOY COMPONENT - A method of heat treating a superalloy component includes solution heat treating the component at a temperature below the gamma prime solvus temperature to produce a fine grain structure. Insulation is placed over a first area to form an insulated assembly that is placed in a furnace at a temperature below the solvus temperature and maintained at that temperature for a predetermined time to achieve a uniform temperature. The temperature is increased at a predetermined rate to a temperature above the solvus temperature to maintain a fine grain structure in a first region, produce a coarse grain structure in a second region and produce a transitional structure in a third region between the first and second regions. The insulated assembly is removed from the furnace when the second region has been above the solvus temperature for a predetermined time and/or the first region has reached a predetermined temperature.08-18-2011
