Abstract

Based on thermodynamic calculations, it is shown that metal melting is an equilibrium process that occurs at a constant temperature. In melting, microcrystals mainly disintegrate into nanocrystals. Metal melt is a twophase system consisting of nanocrystals and atomic gas. Nanocrystals ranging in size from one to hundreds of nanometers exist stably in the metal melt.
