Abstract

A precise calculation is made of the temperature distribution in two adjacent phases when the interface position is caused to vary harmonically with time under a thermal driving force. The departure from equilibrium at the interface required for ``uniform advance'' kinetics is included in the analysis. It is found that the interface temperature is exactly 180° out of phase with the freezing velocity and that the amplitude of the interface motion displays dispersion with frequency. The consequences of having phases of different density is evaluated. The analysis is discussed primarily from the viewpoint of solid—liquid interface motion.
