Nanocrystalline face-centred-cubic (FCC) materials show unique mechanical properties. In this regard, an interesting but controversial discovery is that nanocrystalline FCC materials with high stacking-fault energy (SFE), such as aluminum (Al), exhibit a novel mechanism of deformation. In particular, both molecular dynamic simulations and high-resolution transmission electron microscopy observations show that for nanocrystalline Al mechanical twinning plays an important role in the deformation…

In this article, we readdress the question of homogeneous nucleation of dislocation loops in the context of nanocrystalline materials. In this case, the commonly adopted assumption of an infinite
Sample-size-dependent surface dislocation nucleation in nanoscale crystals
Abstract 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 only

Dislocation processes in the deformation of nanocrystalline aluminium by molecular-dynamics simulation
It is demonstrated that, in contrast to coarse-grained Al, mechanical twinning may play an important role in the deformation behaviour of nanocrystalline Al, and large-scale molecular-dynamics simulations are used to elucidate this intricate interplay during room-temperature plastic deformation of model nanocrystaline Al microstructures.
Deformation Twinning in Nanocrystalline Aluminum
Transmission electron microscope observations that provide evidence of deformation twinning in plastically deformed nanocrystalline aluminum underscore a transition from deformation mechanisms controlled by normal slip to those controlled by partial dislocation activity when grain size decreases to tens of nanometers, and they have implications for interpreting the unusual mechanical behavior of nanocrystaline materials.

Measurements of plastic yielding for single crystals of micrometer-sized dimensions for three different types of metals find that within the tests, the overall sample dimensions artificially limit the length scales available for plastic processes.
Onset of plasticity in gold nanopillar compression.
It is demonstrated that slip nucleates at surface features for which the amplitude of thermal vibrations is a maximum, which leads to a yield stress which can be either a linear or parabolic function of temperature, depending on the strength with which atoms are bound to the surface.

If, in a multiply‐connected elastic solid, discontinuities are permitted across a stationary barrier in either the strain or its first derivatives or both, dislocations of a more general type than
