Popis: The influence of changes in lattice constant and binding energy of surface atoms of binary alloys on sputtering of deformed areas has been examined by a molecular-dynamic method. As a target we chose materials, which are used for coin manufacturing: tin bronze Cu 87 Sn and Ni–Fe alloys with different component concentration. Energy and spatial distributions of sputtered atoms before and after deformation are studied for mono- and polycrystals by considering segregation and heating of targets. The results obtained can be used for improving procedures for detecting deformed areas hidden under the surface of different products.
