A Model of Enhanced Strain Rate Sensitivity in Nanocrystalline and Ultrafine-Grained Metals
A model is suggested that describes enhanced strain rate sensitivity of nanocrystalline and ultrafine-grained metals. Within the model, plastic deformation of such metals incorporates dislocation transmission across grain boundaries (GBs) in the stress fields of dislocation pileups, the emission of...
