The competition between dislocation slip and deformation twinning in body-centered cubic
(BCC) nanocrystals can be strongly influenced by the deformation conditions. In this study …

The deformation behaviour of twinned FCC nanowires has been extensively investigated in
recent years. However, the same is not true for their BCC counterparts. Very few studies …

Twinning is a fundamental deformation mode that competes against dislocation slip in
crystalline solids. In metallic nanostructures, plastic deformation requires higher stresses …

Twinning is commonly activated in plastic deformation of low stacking-fault face-centered
cubic (Fcc) metals but rarely found in body-centered cubic (Bcc) metals under room …

Nanomaterials often surprise us with unexpected phenomena. Here, we report a discovery
of the anti-twinning deformation, previously thought impossible, in nanoscale body-centered …

Molecular dynamics simulations were performed to demonstrate the synergistic effects of the
extrinsic size (nanowire length) and intrinsic size (twin boundary spacing) on the failure …

Twinning in body-centered cubic metals is typically attributed to glide of 1/6< 111>
dislocations originated from material defects. Here we report an alternative mechanism for …

Body-centred cubic (BCC) metals are known to have unstable intrinsic stacking faults and
high resistance to deformation twinning, which can strongly influence their twinning …

The role of twin orientation in mechanical behaviors of nanomaterials is drawing increasing
attention. In this paper, atomistic simulations on the tensile deformation of twinned Cu …

Device miniaturization requires the bending of nanowires (NWs) on the nanoscale. To
explore the mechanical behavior the mechanisms of plastic deformation of nickel nanowires …
