Abstract
A number of models have been proposed in order to describe the geometr ical aspects of the progress of superplastic deformation. Geometrical models of superplastic flow considering sliding of individual grains a nd models of cooperative grain boundary sliding (CGBS) have been criti cally analyzed. Experimental evidence supporting models that treat CBG S as a sequential sliding of grains has been presented. This approach is further developed in terms of movement of cellular dislocations in two-phase materials.
