Abstract
The results of targeted modification of the structure and properties of copper nanotubes by accelerated O 3+ ions at a fluence of 1 × 10 9 to 5 × 10 11 cm −2 with an energy of 1.75 MeV/nucleon are reported. XHray diffraction methods have been used to study the dynamics of changes in the crystallite shape, dislocation density, and the orientation of copper nanotubes before and after irradiation. It has been shown that irradiation with accelerated ions has a significant effect on the change in texture coefficients and dislocation density. At a fluence of 1 × 10 10 cm −2 or higher, the accumulation of oxygen in the nanotube structure is observed, which leads to the appearance of oxide compounds.
