Analysis of the influence of vacancy-solute interaction on diffusion of atomic monomers and clusters

P. Warczok, J. Zenisek and E. Kozeschnik

In the present paper, we investigate the dependence of the diffusional mobility of single solute atoms as well as clusters of atoms on the vacancy-solute binding characteristics with the Monte Carlo (MC) method. Existing work, mainly based on first-principles calculations and atomistic simulations, is reviewed first. Then, we compare these results to our simulations performed with MC and explore these effects in the light of macroscopic diffusive fluxes and atomic clusters movement in the sense of Brownian motion. Finally, we propose a numerical method for incorporation of the movement and potential collisions of clusters in a precipitation kinetics framework.
