Influence of strain rate on plasticity of materials

Abstract

The identity of X-ray radiographs of plastically deformed annealed and unannealed crystals indicates that elastic changes in the orientation of neighboring sections of a plastically deformed unannealed crystal play an insignificant role in the formation of tails on the radiographs. The investigation of the nature of rotation led to a detailed study of tails on X-ray radiographs, since the reorientation of individual sites in a deformed crystal is most reliably established by means of X-ray radiographs. From a crystal, whose lattice is distorted, X-rays with blurred and split spots are obtained, asterisms and bridges between bright spots appear.
