The results of research on the defect structure and microhardness in α -Fe irradiated by a pulsed high-power ion beam are presented. The results are obtained with the use of positron annihilation, electron microscopy, and a nanoindenter. It is shown that the pressure gradient and the depth of formation of the shock wave front in α -Fe irradiated by a high-power ion beam have an influence on the formation and location of the maximum of the dislocation density and microhardness in the modified layer.
