The nature of dislocation sources in small-scale metals is critical to understanding and
building models of size-dependent crystalline strength at the nanoscale. Pre-existing …

The strength of true metallic nanowires and nanopillars (diameters below 100nm) is known
to be higher than the strength of bulk metals and is most likely controlled by dislocation …

We demonstrate strain-rate sensitivity emerging in single-crystalline Cu nanopillars with
diameters ranging from 75 up to 500nm through uniaxial deformation experiments …

The mechanical behavior of single crystalline aluminum nano-pillars under uniaxial
compression differs from bulk Al in that the former is characterized by a smoother transition …

The ideal strength of crystalline solids refers to the stress at elastic instability of a
hypothetical defect-free crystal with infinite dimensions subjected to an increasing load …

In situ tensile tests of Cu single crystalline nanowires in a high-resolution transmission
electron microscope reveal a novel effect of sample dimensions on plasticity mechanisms …

The finite-temperature mechanical strength of nanoscale pristine metals at laboratory strain
rates may be controlled by surface dislocation nucleation, which was hypothesized to be …

The mechanical properties and plastic deformation mechanisms of metal nanowires have
been studied intensely for many years. One of the important yet unresolved challenges in …

The plastic deformation and the ultrahigh strength of metals at the nanoscale have been
predicted to be controlled by surface dislocation nucleation. In situ quantitative tensile tests …

For bulk face-centered cubic metals in conventional tests, the effects of sample shape on the
yield stress are negligibly small, and the strength dependence on temperature is very weak …
