On the basis of the thermodynamics of irreversible processes, possible cross-effects in isothermal diffusion in solids with internal surfaces were analyzed. Expressions were obtained for the fluxes of components, and for the fluxes of a new thermodynamic parameter: specific area of internal surface per unit volume or mass of the medium. An analysis was made of these relationships, and of the relationships between stresses and strains for various cases. It was assumed that diffusion occurred via interstitial sites.
