Abstract

Based on a simple theoretical model, it is demonstrated how the two different relaxation times of phonon and atomic diffusion systems drive kinetic behavior. The calculations are conducted within the framework of Cluster Variation Method on the diffuse intensity spectrum due to short range ordering during the relaxation process. It is shown that kinetic feature is emerged depending upon the competition between the external cooling and internal diffusion rates. A mathematical framework is proposed to generalize the present study.
