Аннотация

The results of an electron microscopy study of alloy 1441 of the Al-Cu-Mg-Li-Zr-Mn system after cold rolling (e{open} = 72%) and subsequent irradiation with a powerful pulsed ion beam (70%C+ + 30%H+) in the pulsed-periodic mode (τ = 80 ns, f = 0. 1 Hz) and under the conditions of the generation of only one pulse (τ = 180 ns) are considered. The ion energy was 180 keV. It is shown by transmission electron microscopy that low irradiation doses D = 1 × 1014-2 × 1015 cm-2 of cold-worked alloy 1441 cause a noticeable transformation of a cellular dislocation structure formed in it. It is shown that, as the ion current density increases in the pulse, the intensity of structural transformations in the alloy increases.
