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 …

Nearly all metals, alloys, ceramics, and their associated composites are polycrystalline in
nature, with grain boundaries that separate well-defined crystalline regions that influence …

Grain boundary velocity has been believed to be correlated to curvature, and this is an
important relationship for modeling how polycrystalline materials coarsen during annealing …

Grain boundaries exhibit phase-like behavior in which their structure, chemistry and
properties may change discontinuously at critical values of thermodynamic parameters such …

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 …

The question of the formation mechanism of annealing twins in face-centered cubic metals
and alloys, which is still not resolved in spite of the fact that the existence of these defects is …

In polycrystalline materials, grain growth occurs at elevated temperatures to reduce the total
area of grain boundaries with high energy. The grain growth rate usually slows down with …

As nanocrystalline (NC) materials exhibit many unique properties, which are often superior
to the properties of their coarse-grained counterparts, they offer significant potential for use …

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