ABSTRACT:
A stack of titanium sheets are placed on a worktable in a vacuum chamber. One of the mating surfaces of each pair of mating surfaces has had a stop off material applied in a desired pattern to prevent diffusion bonding. A pump evacuates the vacuum chamber and heaters heat the stack to evaporate volatile binder from the stop off. When all the binder has been removed the worktable is moved relative to an electron beam gun to weld the edges of the sheets together to form a sealed assembly. The volatile binder is removed quickly and oxidation of the titanium is prevented during baking out of the binder. The sealed assembly is then heated and externally pressurised to diffusion bond the sheets together. The integral structure is then heated and internally pressured to superplastically form one of the sheets to produce an article of predetermined shape.
