We demonstrate that grain boundaries (GBs) behave as Brownian ratchets, exhibiting
direction-dependent mobilities and unidirectional motion under oscillatory driving forces or …

The mechanical properties of a material are affected by the kinetics and thermodynamics of
the grain boundaries (GBs) present in their domain. Various research works, both …

Nanometer size grains, solid solution strengthening, low temperatures, and a high density of
nanotwins can provide significant strengthening to a material. Nevertheless, under loading …

Grain boundaries (GBs) influence a wide array of physical properties in polycrystalline
materials and play an important role in governing microstructural evolution under extreme …

Observations of microstructural coarsening at cryogenic temperatures, as well as numerous
simulations of grain boundary motion that show faster migration at low temperature than at …

Synthetic driving force based molecular dynamics simulations are used to evaluate the grain
boundary velocities for an incoherent Σ3 [111] 60°{11 8 5} GB in elemental nickel and its …

Molecular dynamics simulations are used to examine the migration behavior of one
incoherent twin, a Σ3 (11 8 5)/(8 11 5) grain boundary. The boundary is known to exhibit non …

Grain boundaries often develop faceted morphologies in systems for which the interfacial
free energy depends on the boundary inclination. Although the mesoscale thermodynamic …

Synthetic driving force molecular dynamics simulations were performed to examine anti-
thermal mobility in the incoherent Σ3 [111] 60°{11 8 5} grain boundary in a model FCC …

Atomistic simulations provide the most detailed picture of grain boundary (GB) migration
currently available. Nevertheless, extracting unit mechanisms from atomistic simulation data …
