Development of Spatial Correlations during Diffusional Late-Stage Phase Transformations in Stressed Solids

Abstract
We examine the dynamics of the development of interparticle spatial correlations during the later stages of a first-order phase transformation in which the second-phase particles generate a stress field. Through an analysis of the diffusional and elastic interactions between two particles, it is shown that the long-ranged motion of the centers of mass of the particles within the solid is an important component in the development of the experimentally observed spatial correlations.
