A Numerical Simulation of Superplastic Double-Sided Roll Forming of Discal Parts

Abstract:

A numerical simulation of superplastic double-sided roll forming of aluminium alloy discal part is presented in this paper. The numerical results show strain and strain rate distribution, grain refinment, transformation from general hot forging to superplastic forming. The superplastic forming includes two stages: the small deformation stage is controlled by plastic deformation and grain refinment, and the large deformation stage superplastic deformation is main deformation mechanism.
