The combination of ion irradiation and nanoindentation presents a vast field of research which includes not only experiments but also modeling that can reveal the features of the deformation behavior of materials at the micro- and nanoscale. The modeling carried out in the work made it possible to evaluate the correspondence between the strength parameters measured in the course of tensile tests of macrosamples irradiated with neutrons and the results of dynamic instrumental indentation of the samples that were used in the experiment on ion irradiation. The increase in hardness calculated during the simulation turned out to be comparable with that obtained experimentally, which indicates efficiency of the technique. The plastic behavior inherent in the samples subject to the experiment which manifests itself in a decrease in the height of the rolls with an increase in the irradiation dose was also confirmed in the simulation.
