In order to detect the behavior of dislocations at high rates of strain, time-resolved measurement of the ultrasonic attenuation under dynamic plastic deformation was made. The experimental technique, the theoretical background of this method and the results of the measurements made for polycrystalline aluminum are presented together with brief discussion.
