Abstract
A model has been proposed for calculating optimal grain size dopt for superplastic deformation of nanoand microcrystalline (NMC) materials produced by severe plastic deformation (SPD). The model is based on the concepts of the theory of nonequilibrium grain boundaries in metals. The dependences of d...
