Scaling of domain size during spinodal decomposition: Dislocation discreteness and mobility effects

In this letter, we examine the effects of discrete mobile dislocations on spinodal decomposition kinetics in lattice mismatched binary alloys. By employing a novel continuum model, we demonstrate that the effects of dislocation mobility on domain coarsening kinetics can be expressed in a unified manner through a scaling function, describing a crossover from t1∕2 to t1∕3 behavior.
