Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

Grain boundaries in polycrystalline materials migrate to reduce the total excess energy. It
has recently been found that the factors governing migration rates of boundaries in bicrystals …

Grain boundaries (GBs) play an important role in the mechanical behavior of polycrystalline
materials. Despite decades of investigation, the atomic-scale dynamic processes of GB …

Grain boundary (GB) migration plays an important role in modifying the microstructures and
the related properties of polycrystalline materials, and is governed by the atomistic …

Dense networks of deformation twins endow metals and alloys with unprecedented
mechanical properties. However, the formation mechanism of these hierarchical twin …

Phase transitions are a common phenomenon in condensed matter and act as a critical
degree of freedom that can be employed to tailor the mechanical or electronic properties of …

Grain boundary (GB) migration associated with grain growth and recrystallization
encounters lattice defects frequently, while the atomistic mechanisms of GB-defect …

A detailed monitoring of atomic-scale processes accomplishing grain rotation is important for
understanding the deformation mechanisms in nanocrystalline metals. However, direct …

Grain boundary (GB) structural change is commonly observed during and after stress-driven
GB migration in nanocrystalline materials, but its exact atomic scale transformation has not …

We show that chemistry can be used to trigger a nanofaceting transition. In particular, the
segregation of Ag to an asymmetric tilt grain boundary in Cu is investigated. Aberration …
