ABSTRACT:
A retort for use in diffusion bonding preselected areas of a stack of metallic sheets during a process of fabricating metallic sandwich structures. The retort facilitates a contamination-free, evacuated environment in which a plurality of sheets of titanium aluminide can be joined to one another at selected areas to form a pack. The process of joining embraces a technique of elevated temperature gas diffusion bonding. Subsequent superplastic expansion of the bonded blanks is employed to form desired sandwich structures.
