Summary:Title screen
Atomic structure changes of surface layers of aluminum crystallites after ion bombardment are studied. Themolecular dynamics simulation is used for the investigation of structural changes in irradiated crystallites. The results ofcalculations show that orientation of the irradiated surface and preliminary elastic deformation has a significant impact onfeatures of formation of the atomic structure in the ion-modified layer. The minimal changes in the surface layer areobserved at the irradiation of surfaces with {100} lattice planes. A sufficiently great number of stacking faults wasformed under irradiation of {111} and {110} surfaces. On the base of the simulation, it can be expected that the processof the surface structure fragmentation is most favorable for cases when surfaces with the {111} and {110} lattice planesare irradiated. An increase in the degree of preliminary elastic deformation can reduce the energy of incident particles,which is necessary for fragmentation of the surface structure.
