Abstract
Experimental observations of morphological and chemical changes in superpla stically deformed samples of Zn-22% Al alloy have been carried out. It has been shown that the superplastic deformation exerts a strong influence on t he process of diffusional mass transfer. A conclusion has been made that th e specific feature of the superplastic deformation-development of bands of the co-operative grain boundary sliding-may explain the mechanism of such a n influence.
