Abstract:
The expressions for the interfacial tension on plane and curved solid-liquid boundaries and for the distance between the equimolecular separating surface and the separating surface corresponding to a zero excess free energy of the system have been obtained in terms of a thermodynamic approach using two separating surfaces. For 50 metals, the numerical calculations have been performed for plane boundaries and solid spherical nanoparticles in their own melts in the dependence on their sizes at the melting temperatures.
