Abstract

Amodel of the elastoplastic behavior of commercial titanium is developed with allowance for the evolution of the microstructure of Ti Grade-4 Ti under equal channel angular pressing with application of the Conform process. The evolution of the mean dislocation density, of the dislocation density in the body and on the boundaries of grains, and of the density of mobile dislocations is studied. The concentrations of strain-induced vacancies, the speeds of gliding dislocations, and the angles of off-orientation between neighbor grains are determined, which widens substantially the understanding of the mechanisms of the elastoplastic behavior of Ti Grade-4 under severe plastic deformation.
