Gibbs equilibrium conditions and the thermodynamic limit

In the present work we critically examine a structural model of a heterophase body, whose equilibrium is described by the equations of Gibbs equilibrium conditions. We demonstrate that these equilibrium conditions describe the behaviour of the heterophase body in a thermodynamic limit. Additionally, these equations can be viewed as the phase transition conditions from any homophase system that make up the heterophase body. In light of the proposed interpretation of Gibbs equilibrium conditions, we offer a new way to define phase transition temperature.
