| Abstract: | Mechanical properties of metals are most sensitive to the presence of point defects. The influence of point defects on the
kinetics of plastic deformation is highly diversified: the point defects can be the main carriers of plastic deformation (diffusion
creep, crowdion plasticity, etc.), can imitate the velocity of nonconservative motion of dislocations, and can serve as centers
of pinning of dislocations.
