Abstract

A set of equilibrium thermodynamics relationships are developed to account for the effects of fixed levels of interstitials and vacancies on phase free energy in binary alloys. Such defects would typically be found in alloys under irradiation, and could account for shifts in phase solubility limits and stable temperature ranges. While the total defect concentrations are fixed, no external constraints are placed on the distribution in types of interstitials. These distributions and the alloy phase compositions are allowed to adjust to minimize the system free energy and predict the constrained thermodynamic equilibrium phase structures. Calculational results are presented for three binary alloy systems, iron-chromium, titanium-zirconium, and manganese-silicon.
