Study of the influence of vacancies and vacancy complexes on the yield limit of Al subjected to strain aging

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. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 18–20, March, 2008.
