Abstract

A hollow vessel can be made by fabricating a preform from welded together sheets of superplastically deformable metal and then expanding the preform to the required shape of the vessel but the necessary weld lines can be a source of weakness. Herein, a vessel is made by superplastic deformation of a preform made by machining a hollow space within a solid piece of metal or by extruding a tubuler preform and blanking off at least one of its ends.
