ABSTRACT:
The present invention relates to a method for diffusion bonding metallic detail parts to form a structural component. This invention presents an efficient low cost method of establishing and maintaining the required intimate surface contact for solid state diffusion bonding. This contact is achieved by configuring the metallic details such that sufficient stability is present to permit applying bonding forces sufficiently great to plastic flow the to-be-joined surfaces into intimate contact. The self-stability of the detail parts eliminates the need for support tooling and the plastic flow to achieve intimate contact eliminates the need for close tolerance preparation of the detail parts. This method is particularly applicable to the fabrication of hollow internally stiffened structural components in which the shell skins are non-parallel; such as turbofan/turbojet engine vanes and blades.
