TL;DR: 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.

TL;DR: Measurements of the plastic flow of the model body-centered-cubic metal tantalum made under conditions of high pressure and strain rate and the effect of grain size is found to be negligible for grain sizes >0.25 μm sizes.

TL;DR: In this paper, the authors present a mechanical test methodology to explore specimen size effects in Ni 3 Al, where the overall test sample dimensions artificially limit the volume for substructure evolution and hence the availability of jogs/kinks along individual dislocation lines.

TL;DR: In this article, the competition between dislocation slip and twinning in tantalum single crystals has been investigated utilizing a crystal level twinning model and the results from gas gun recovery experiments conducted at peak normal stresses of 25 and 55 GPa.

TL;DR: In this paper, a single-stage light gas-gun was used to launch a thin flyer plate into the samples, generating a region of intense tensile stress on a plane normal to the impact direction.
