Significant progress in our understanding of plasticity in body-centered cubic (bcc) metals during the last decade has enabled rigorous multiscale modeling based on quantitative …
The interaction of dislocations and solute atoms is key to understanding crystal plasticity in alloys. I present a kinetic Monte Carlo (kMC) simulation of the glide of a screw dislocation in …

Abstract 1/2111 screw dislocations that possess non-planar cores and thus a high lattice friction (Peierls) stress control the plastic deformation of pure bcc metals. In this paper we …
In this article, we present a time-dependent deformation mechanism for fcc metal single crystals in which the resulting deformation is produced by the cumulative effect of dislocation …

We have performed atomistic simulations of an isolated screw dislocation in bcc Mo and W using Bond Order Potentials [Gröger, 2007]. Based on these results we formulated an …
Plasticity of body-centered cubic (bcc) metals is atypical at low temperatures, caused by the important lattice friction of 1/2< 111> screw dislocations. In this paper, we present a yield …
