Abstract

A theoretical description of the plastic deformation of nanostructured and polycrystalline metals through paired nanotwinning on grain boundaries has been proposed. Within the micromechanical approach developed, deformation nanotwins are formed as a result of successive plastic shears. The energy characteristics and critical stresses of paired twin nucleation in titanium are calculated.
