Abstract Scope |
Diffusion-driven processes are crucial for designing more efficient industrial processes that enable enhanced tuning of alloy microstructures. A supersaturation of vacancies can enhance this control; it has been shown that when vacancies cluster and nucleate into voids, they can either deplete or segregate solute atoms in their vicinity, depending on the solute-vacancy binding energy. The segregation of solute near vacancy clusters may lead to later intermetallic precipitation, resulting in the manufacture of alloys with higher strengths. Using transition interface sampling to simulate reactive void nucleation trajectories, the mutual solute-vacancy relation in magnesium binary alloys is studied. To investigate the role of vacancy aggregation in solid-state precipitation, two different solute species with opposite vacancy binding affinities are considered and compared.
