Results of the laser treatment of ultrafine aluminum alloys 1420 and 1421 are presented. As a result of laser irradiation, a significant decrease in the interplane distance is observed in the alloys, indicating that admixture atoms diffuse to grain b

It is demonstrated that the interaction of laser radiation with ultrafine-grained aluminum alloys substantially differs from that with analogous coarse-grained materials, which accounts for a change in the shape of holes formed during precise laser m

The formation of holes under the action of single laser pulses was studied in thin-sheet samples of aluminum alloy 1420 with ultrafine-grained (UFG) and coarse-grained (CG) structures. It is established that, at the same laser pulse energy, a hole in
