Recent experiments on nanostructured materials, such as nanoparticles, nanowires,
nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of “ultra-strength” …

The influence of material and choice of interatomic potential on the interaction between an
a/2〈 110〉{111} screw dislocation and a Σ3 {111}〈 110〉 coherent twin boundary (CTB) is …

The interactions between dislocations and twin boundaries (TBs) are significantly affected
by both intrinsic material properties and extrinsic factors, including stacking fault energy, the …

The strengthening effect of twins in nanocrystalline metals has been reported both in
experiment and simulation. While twins are mostly considered as effective barriers to …

In this research parallel molecular dynamics (MD) simulations have been performed to study
the deformation behavior of nanocrystalline copper samples with embedded nanotwins …

Starting from a semi-empirical potential designed for Cu, we have developed a series of
potentials that provide essentially constant values of all significant (calculated) materials …

We investigate the dependency of strain rate, temperature and size on yield strength of
hexagonal close packed (HCP) nanowires based on large-scale molecular dynamics (MD) …

Nanotwinned metals have the potential for use as structural materials by virtue of having a
combination of high strength as well as reasonable ductility and damage tolerance. In the …

The deformation mechanisms of nanotwinned Cu subjected to nanoscratching are
investigated by means of molecular dynamics simulations. Scratching simulations on …

Nanocrystalline and nanotwinned metals exhibit ultrahigh strength but suffer from low
ductility due to the absence of the strain hardening effect. Here, we report sustained strong …
