Nanoindentation based techniques were significantly enhanced by continuous stiffness
monitoring capabilities. In essence, this allowed to expand from point-wise discrete …

Non-Arrhenius grain boundary migration, sometimes referred to as antithermal migration
where temperature and GB velocity values are inversely related to each other, is examined …

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 …

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 …

A novel dislocation-density-based crystal plasticity model for nanocrystalline face-centered
cubic metals is developed based on the thermally-activated mechanism of dislocations …

In this article, molecular dynamics simulations are used to understand how a nickel bicrystal
with faceted incoherent Σ3 grain boundaries responds to uniaxial tensile loading. The …

Grain growth accompanied by shear band formation shortens lifetime of nanostructured
metals upon cyclic loading. Although the occurrence of structural instabilities was reported …

The difficulty to reveal trap** sites of hydrogen in metals, how hydrogen interacts with
lattice defects and potentially changes their behavior, still prevents a generalized …
