We compare the uniaxial tensile behavior of µm-scale cast silver tensile specimens at strain
rates of 10− 3 s− 1 and 2 s− 1 to find no major impact of the strain rate on either of the flow …

Monocrystalline microwires of silver are produced by means of a novel casting process that
combines precise mold production by silicon microfabrication with molten metal pressure …

The plastic deformation of small-scale face-centered cubic metals exhibits intermittent slip
burst events that appear on stress-strain curves as sudden strain jumps and/or load drops …

Intermittent plastic deformation in micro-crystals was resolved in both space and time,
yielding velocity profiles that peak in a range from approximately 1 μm/s to 100 μm/s. The …

Metals are known to exhibit mechanical behaviour at the nanoscale different to bulk
samples. This transition typically initiates at the micrometre scale, yet existing techniques to …

Micron-scale single-crystalline materials deform plastically via large intermittent strain bursts
that make the deformation process non-deterministic. Here we investigate this stochastic …

Low temperature (77K, 243K and 255K) mechanical tests were carried out at strain rates
between 7.10− 4s− 1 and 5.10− 2s− 1 on pure ultrafine grained (UFG) copper (grain size …

A microcasting process is used to produce high aspect ratio (> 30) monocrystalline pure
aluminium wires with a diameter between 14 and 115 µm. The role of thermal activation in …

Prior to macroscopic yielding, most materials undergo a regime of plastic activity that cannot
be resolved in conventional bulk deformation experiments. In this pre-yield, or micro-plastic …

A numerical algorithm is developed for the integration of the constitutive equations of rate-
dependent crystal plasticity theory. The algorithm is based on a weighted residual method …
