Current developments in kinetic and thermodynamic stabilization of grains in nanostructured
metals, alloys, and compounds are generalized and discussed in detail. As applied to the …

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 …

Abstract High-power, short-duration, laser-driven, shock compression and recovery
experiments on [001] silicon unveiled remarkable structural changes above a pressure …

The important class of grain boundary (GB) complexions includes the few nanometer thick
layers having composition which strongly differs from that of the abutting grains. Such GB …

Zener drag and pinning in composites reinforced with cylindrical particles is investigated
using three-dimensional phase-field simulations. Detailed systematic studies clarify the …

Solute segregation is a crucial means of stabilizing nanostructured alloys, and at very small
grain sizes, this requires consideration of triple junctions (TJs), which attain a meaningful …

Targeted doping of grain boundaries is widely pursued as a pathway for combating thermal
instabilities in nanocrystalline metals. However, certain dopants predicted to produce grain …

Surface triple junctions (STJs), ie, the termination lines of grain boundaries at solid surface,
are the common line defects in polycrystalline materials. Compared with planar defects such …

Severe plastic deformation drives bulk materials far away from equilibrium and thus opens
up a new opportunity to explore hitherto uncharted regions of structure-property correlations …

Abstract A Mg-8.2 Gd-3.8 Y-1.0 Zn-0.4 Zr (wt.%) alloy is processed by solution treatment and
high pressure torsion (HPT) at room temperature to produce a nanostructured light material …
