摘要：

Based on the thermodynamic and thermophysical properties of bulk materials, Gibbs free energy for nanostructured materials is obtained and used to study the size-dependent melting point depression phenomenon. The effects of volume change due to fusion, the thermal expansion and the temperature dependency of surface free energy of bulk materials on the melting point depression are investigated. Conversely, the solid surface free energy of bulk materials is also researched by means of the size-dependent melting temperature of nanostructured materials. (C) 2010 Elsevier Ltd.
