摘要： A heat treatment technique may include heating an alloy component to a temperature above a transition temperature of the alloy or heating an alloy component to a temperature below the transition temperature of the alloy. The heat treatment technique further may include cooling a first portion of the alloy component at a first cooling rate, and cooling a second portion of the alloy component at a second cooling rate different than the first rate. The first cooling rate may result in formation of a plurality of first precipitate phase domains comprising a first average size in the first portion, and the second cooling rate may result in formation of a plurality of second precipitate phase domains comprising a second average size in the second portion. The average size of the first precipitate phase domains may be different than the average size of the second precipitate phase domains.

摘要： A method of heat treating a superalloy component comprises solution heat treating the component at a temperature below the gamma prime solvus temperature to produce a fine grain structure in the component. Insulation is placed over a first area of the component to form an insulated assembly. The insulated assembly 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 in the component. 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, to produce a coarse grain structure in a second region and to produce a transitional structure in a third region between the first and second regions of the component. The insulated assembly is removed from the furnace when the second region of the component has been above the solvus temperature for a predetermined time and/or the first region of the component has reached a predetermined temperature.

摘要： A method for preparing rings having an integral stiffening geometric pattern on its outer surface is disclosed. The method employs a variation of the drum rolling process, but it incorporates unique tooling for providing the pattern, preferably comprising a plurality of segments which fit together to define a ring, the inner surface of which presents the desired pattern toward the center of the ring. A unique drum arrangement includes inner and outer components for locking the segments in place and for providing the structural integrity required for the final drum rolling operation. A cylinder, for example an aluminum or aluminum alloy cylinder, is placed in the drum, the cylinder being preformed and presized to fit concentrically within the segment defining ring. Following heating of the assembly to forming temperature, the cylinder is radially expanded using a sizing tool, and the assembly is then placed over a mandrel in preparation for drum rolling. In the illustrated embodiment, an isogrid pattern of recesses is formed in the segments, so that upon completion of drum rolling and disassembly of the drum and segments, a raised, integral isogrid stiffening pattern is provided on the outer ring cylinder surface.
