Abstract
This invention relates to a process of forming components having selectively thickened regions from superplastically formable and diffusion bondable materials. The said selected thickening is achieved by positioning metal matrix composite plies between the interior surface of each of the formed skin sheets of the component and the sheets which will form the internal cells, superplastically forming the cells, and then diffusion bonding the component to form a metallurgically bonded structure.
