Abstract
According to a unified thermodynamic scheme we derive the general kinetic equation ruling the phasefield evolution in a binary quasiincompressible mixture for both transition and separation phenomena When diffusion effects are negligible in comparison with source and production terms a solid–liquid phase transition induced by temperature and pressure variations is obtained In particular we recover the explicit expression of the liquid–pressure curve separating the solid from the liquid stability regions in the pressure–temperature plane Consistently with physical evidence its slope is positive negative for substances which compress expand during the freezing process
