Abstract

 In this paper authors show by the analysis the change in the free energy of the phase transitions.
In phase transitions observed release of the latent heat of crystallization, the redistribution of solute in the system and the formation of the surface of the new phase.
Localization of latent heat of crystallization on the phase boundary leads to a significant overheating surface of the solid phase.
In this regard, a more probable mechanism of crystallization, this occurs at lower values of the specific Gibbs potential.
This is accompanied by the cost of thermal energy on the ordering of the structure, redistribution of substance, the formation of new interfaces.
