While the grain size effect (GSE) is universally observed in polycrystalline metals and alloys,
extended dislocation pileups (DPUs) at grain boundaries (GBs) are rarely observed …

Mesoscopic obstacles (eg, precipitates) serve as an important strengthening and hardening
mechanism in metallic alloy systems. Several example material systems include Mg and Al …

A stochastic discrete slip approach is proposed to model plastic deformation in submicron
domains. The model is applied to the study of submicron pillar (D≤ 1 μ m) compression …

Owing to their excellent mechanical and electrical properties, 2D–3D composites have
attracted extensive attention. Their novel 2D–3D structure challenges the prevailing …

Hetero-boundary-affected regions (HBARs) are widely observed in metallic materials and
believed to play important roles in heterostructured materials that are currently attracting …

Pristine specimens yield plastically under high loads by nucleating dislocations. Since
dislocation nucleation is a thermally activated process, the so-called nucleation-controlled …

The mechanical properties of a material are intimately related to its microstructure. This is
particularly important for predicting mechanical behavior of polycrystalline metals, where …
