The motion of localized deformation sites in mono- and polycrystallites of metals and alloys is investigated experimentally at the stages of easy slip and linear strain hardening. The wave nature of localization of deformation at these stages of plastic flow is established, and the velocity of waves and their dispersion relation are determined. The scale effect and the dependence of the localized deformation wavelength on the grain size are investigated. A qualitative interpretation of the results obtained is proposed.
