“…Spinodal decomposition can occur for large supersaturation. Local segrega tion in solutes can be enhanced by the inverse Kirkendall effect [15,36]. Because the diffusion of vacancies induces a solute flux in the opposite direction, solute elements that diffuse the most rapidly will be depleted at sinks (grain boundaries, dislocations, cavities and interfaces) and, on the contrary, slower diffusers will segregate at sinks.…”
