A phenomenological theory of transformation superplasticity is presented from the point of view of thermomechanics. The stretching tensor and entropy density are assumed to be decomposed into the elastic part and the part due to the superplastic process. The constitutive equations for the superplas
## Abstract The coarse‐grained Al alloy AA5182 exhibits poor superplasticity with a maximum elongation to failure not exceeding 220 % at 450 °C and at 10^‐2^ s^‐1^. The low values of the strain rate sensitivity indicate that the dislocation velocity is quite high and necking is developed quite soon
