Dynamic strain aging of the materials characterized by the Peierls plasticity mechanism

Аннотация

A synergetic model is proposed to describe the influence of dynamic strain aging on the plasticity of materials that is controlled by the Peierls barriers overcome by dislocations. The immobilization of dislocations by the impurities concentrated in the dislocation cores is taken into account. The behavior of calculated deformation curves is studied as a function of the material parameters and the mechanical test conditions.
