By thermally cycling through their transformation temperature range, polymorphic materials can be deformed superplastically through internal-stress superplasticity, a deformation mechanism relying on the biasing of internal mismatch Transformation stresses by an external stress.  Unlike microstructural superplasticity which relies on grain-boundary sliding, this mechanism is active in coarse-grained materials and in composites. Recent experimental and modeling results are presented on transformation superplasticity of alloys and composites.
