the influence of biaxial strain-induced diffusion anisotropy upon the evolution of extended defects was analyzed. Point-defect diffusion anisotropy was modeled and incorporated into an atomistic kinetic Monte Carlo framework. The annealing of {311} defects was simulated for self-interstitial diffusion anisotropies varying over plausible ranges. From the simulations, it was deduced that diffusion anisotropy had a significant effect upon the competition between defect ripening and dissolution. In particular, it was shown that a plot of {311} density versus {311} mean size could be used to check for the existence of a self-interstitial diffusion anisotropy.
