Abstract
A new size-dependent equation for an interface tension isotherm of spherical nanoparticles in the macroscopic matrix of a binary system is derived. Macroscopically, it transforms into a relationship that associates the concentrations of bulk phases. By making certain assumptions, the Ostwald–Freundlich formula for the solubility of small particles is obtained. Calculations of the interface tension for nanoprecipitates in a Fe–Cr system at 773 K show a reduction in interface tension as their dimensions shrink.
