Abstract Scope |
Solid-state precipitation and growth of intermetallic phases from metal solid solutions are crucial for the design and manufacturing of alloys. Intermetallic precipitation, especially at the nanoscale, is one of the most effective methods for achieving high strength. In magnesium alloys, it has been demonstrated that such microstructures can be achieved via mechanical deformation processing. Notably, elevated concentrations of vacancies arise during such processing methods, potentially playing a crucial role in the nucleation process. However, studying vacancy-solute clustering and its role in void nucleation is not possible using brute force molecular dynamics techniques due to time scale limitations. Transition interface sampling allows for a statistical sampling of the pathways in phase space associated with void nucleation from vacancies, allowing these effects to be quantitatively assessed.
