PHASE DIAGRAM OF ATOM-VACANCY SOLID SOLUTION

摘要

The assumption of the concentration dependence of the energy of formation of vacancy-type defects (VTD) in solids is applied to the procedure of the estimation of the defect interaction parameters. The VTD effective interaction is described by the mixing potential. The sign of this potential characterizes the stability of the VTD-atom ''alloy.'' Employing the example of Nb, we illustrate the ability of the suggested approach to describe the stability of the VTD-atom ''alloy.'' (C) 1996 John Wiley & Sons, Inc. [References: 9]
