Abstract:

A method of forming a part that includes a first component and a second component and which two components are diffusion bonded together. The first component is configured as a pressure component and includes a first bond land surface. The second component is configured as a suction component and includes a second bond land surface. A mandrel is provided that includes a first surface having a contour that mates with at least a portion of the first component and a second surface having a contour that mates with at least a portion of the second component. The first and second components are positioned on the mandrel so that the first bond land surface and the second bond land surface are in mating abutment. The first and second components together with the mandrel are positioned in a die assembly. The die assembly including a first die, a second die and a plurality of fastening members for releasably securing the first die to the second die. The first and second dies are formed of a first material having a first coefficient of thermal expansion. The fastening members are formed of a second material having a second smaller coefficient of thermal expansion. The die assembly is placed in a heating arrangement for a diffusion bonding cycle and this temperature of the heating arrangement is increased to a predetermined temperature. Uniform pressure is applied across an interface between the first and second bond land surfaces of the first and second components.
