Metal nanowires are usually strong but are not able to maintain a high plastic flow due to a lack of strain hardening. In this study, we investigated the tensile deformation of a new category of metal nanowires with hollow interiors by atomistic simulations – the so-called metal nanotubes – and revealed that they possess a combination of ultrahigh strength and plastic flow. In particular, it was found...
The role played by nanoscale twins is becoming increasingly important in order to understand plasticity in nanowires synthesized from metals. In this paper, molecular dynamics simulations were performed to investigate the synergistic effects of stacking fault energy and twin boundary on the plasticity of a periodically twinned face-centered cubic (fcc) metal nanowire subjected to tensile deformation...
