Thermodynamic Equilibria in Two-Phase, Elastically Stressed Ionic Crystals

The conditions for thermodynamic equilibrium in two‐phase, multicomponent, elastically stressed ionic crystals are derived within the realm of phenomenological thermodynamics using a Gibbsian variational approach. Equilibria between a stressed ionic crystal and a fluid and between two elastically stressed crystals possessing a coherent interface are examined, and an expression for the dependence of the electrochemical potential on stress is...
