ABSTRACT:
A superplastically formed part having tailored thickness in particular areas includes a formed blank having a preformed portion and a formed portion. The preformed portion is preformed as a bulge into a recess in a die lid, and then the bulge is reversed into a cavity in a die base as a prethinned area which delivers unthinned portions of the blank for final forming to regions of the die base cavity over which thinned portions of the blank would otherwise be formed and further thinned by final forming.
