Abstract

This paper presents four methods for resolving grooving problems which often occur in the three-piece sandwich parts manufactured from the combined diffusion bonding and superplastic forming processes. Finite element simulations have been first performed to gain some insights of the deformation processes, which virtually eliminate the "cut-and-try" approach to initial designs and processing schedules and also insure that a component may be successfully produced on the first attempt. Experiments on two of the proposed processing methods have also been successfully carried out to verify the numerical results.
