Nanotwinned metals are attractive in many applications because they simultaneously
demonstrate high strength and high ductility, characteristics that are usually thought to be …

This article reviews recent studies on the mechanical properties of cylindrical metallic
nanopillars subjected to uniaxial deformation. Remarkable strengths and very different …

Interfaces play an important role in crystalline plasticity as they affect strength and often
serve as obstacles to dislocation motion. Here we investigate effects of grain and nanotwin …

Nanotwins require little energy to form in metals, but their impact on strength and ductility is
dramatic. New mechanisms of strengthening, strain hardening, ductility, and strain-rate …

We compare the thermal stability of nanotwinned metals to their nanocrystalline
counterparts. The thermal stability of a coherent twin boundary is superior to that of a high …

We have performed in situ scanning electron microscopy tensile experiments and molecular
dynamics (MD) simulations on nominally defect-free single-crystalline Au nanowhiskers. The …

Although nanoscale twinning is an effective means to enhance yield strength and tensile
ductility in metals, nanotwinned metals generally fail well below their theoretical strength …

Metals with a high density of nanometre-scale twins have demonstrated simultaneous high
strength and good ductility, attributed to the interaction between lattice dislocations and twin …

Nanocrystalline metals generally exhibit high strengths and good fatigue resistance. Their
strengthening scales with the inverse of grain size through square root dependence down to …

The small ductility of nanocrystalline metals limits their use in a variety of applications, which
therefore do not benefit from their ultrahigh strength potential.[1, 2] Most thin metallic films …
