Abstract

Mutual influence of the surface segregation of atoms on lattice sites and in interstitials is studied in the self-consistent field approximation. The effect of occurrence of a local surface phase transformation is predicted, which is caused by a local loss of stability of the statistical distribution of atoms of components on the surface due to the presence of interstitial impurity atoms. A theory is constructed for an induced phase transformation for [001] plane of a single crystal of a binary alloy with an fcc lattice whose octahedral interstitials are occupied by interstitial atoms.
