The microstructural configurations that favor early strain localization and fatigue crack
initiation at intermediate and high temperature (400° C–650° C) have been investigated …

We present a new framework to quantify the effect of hydrogen on dislocations using large
scale three-dimensional (3D) discrete dislocation dynamics (DDD) simulations. In this …

Whereas conventional precipitation hardening is well-known to feature a single hardness
peak, recently, double-peak precipitation hardening was observed, where the first peak …

The present work investigates the effects of temperature and strain rate in fcc and bcc
metallic samples subjected to the extreme strain rates, higher than 10 8 s− 1, using large …

Cross-slip of screw dislocations is a dislocation process involved in dislocation structuring,
work hardening, and fatigue. Cross-slip nucleation in FCC solid solution alloys has recently …

We study a continuum model of dislocation transport in order to investigate the formation of
heterogeneous dislocation patterns. We propose a physical mechanism that relates the …

Continuum dislocation dynamics (CDD) aims at representing the evolution of systems of
curved and connected dislocation lines in terms of density-like field variables. Here we …

The present work investigates the effect of crystal orientation and temperature on the size
effect using micro-sized single-crystal bending beams of copper with thicknesses between 1 …

Cross-slip is a dislocation mechanism by which screw dislocations can change their glide
plane. This thermally activated mechanism is an important mechanism in plasticity and …

Plastic deformation largely determines the properties of tribological contacts. To modify such
contacts, it is thus necessary to understand the underlying mechanisms of dislocation motion …
