Investigation of the strains development under pulsed loading showed the decisive role of powerful ultrasonic sample vibrations in the standing wave mode. The effect of mass transfer of atoms and ultrafine hardening phase particles from the matrix material to the spall damage zone on the strain bands microstructure is determined. Rapid cooling of the metal inside the localization bands, the size of which does not exceed several tens of microns, indicates that changes in the phase composition occur as a result of cold deformation.
