A new approach to estimating kinetic rate factors of phase transformations

Abstract

Abstract An original approach is proposed to estimate of the main kinetic factors that determine the rate of phase transformations in condensed matter. These factors define the frequency of atom transitions from different phases during phase transformation induced by undercooling, high pressures or mechanical impact. On the example of crystallization of a model amorphous system, it is shown that this approach gives a correct estimation of the crystal growth and crystal decay rates both at the initial stage of the phase transition and at the stage of coalescence of crystalline structures.
