The atomic mechanisms of structural rearrangements in the near-surface layer of nanosized aluminum under irradiation by high-energy particle beams were studied. The method of molecular dynamics and many-body potentials of interatomic interactions were used to simulate structural changes in a nanocrystallite during irradiation and following modification of the surface layer. Irradiation was simulated by collisions of incident aluminum atoms with surface atoms. The direction of the collisions was perpendicular to the irradiated surface and the kinetic energy of the incident atoms was varied from 60 to 1500 eV in different calculations. The role of internal elastic tension and the crystallographic orientation of the irradiated surface on the features of the structural response of the crystallite were studied.
