Abstract

In this work we propose a stability criterion for superplastic deformation based on geometrical instabilities and microstructural evolution including grain growth and void growth. An optimum strain rate-forming path is derived from the new criterion. Preliminary results are reported on the effects of microstructural evolution on the stability of deformation of the Ti6A14V superplastic alloy. It is shown that the critical strain predicted from the proposed criterion is significantly affected by microstructural evolution.
