Abstract

In the work the influence of vacancy clusters on strength properties of solid-solid interfaces is studied on the base of the thermodynamic approach. The conditions of cluster formation at the interface are obtained and analyzed. A model describing the influence of vacancy clusters in the contacting materials on the surface tension coefficient γ₁₂ of the interface is also developed. The dependences of the contribution of nonequilibrium vacancy clusters in γ₁₂ on a vacancy supersaturation, cluster concentrations, the number of vacancies in clusters, and temperature are analyzed.
