A summary of the experimental facts which a theory of structural superplasticity should account for, is provided. A stress-aided, diffusion controlled, viscous boundary approach is adopted which predicts the correct kinetics and inter-dependence of variables. The activation energy requirement of the model is reconciled with experimental data and the eventual loss of superplasticity is explained. A detailed discussion reveals that the proposed mechanism can explain most of the observations concerning the phenomenon of structural superplasticity.
