Damages induced by thermomechanical cycles in superplastic forming tools

Abstract : In this paper, damages accumulated in superplastic forming (SPF) tools during the forming cycles were investigated in various aspects. Finite element simulations were performed on an axisymmetrie mould of heat resistant cast steel to evaluate thermomechanical stresses and strains during the forming cycles, which cause accumulated residual stress and deformation damage in the mould. The dimensional changes due to microstructure evolution of the tool material were studied on specimens for typical thermal cycles. And high temperature corrosion destroying the surfaces of the tool was investigated too.
