Dislocation loops, nanovoids and Cu-rich clusters (CRPs) are known to represent obstacles
for dislocation glide in neutron-irradiated reactor pressure vessel (RPV) steels, but a …

The line tension $\Gamma $ of a dislocation is an important and fundamental property
ubiquitous to continuum scale models of metal plasticity. However, the precise value of …

Precipitation hardening is investigated using dislocation dynamics (DD) simulations. Unlike
classical approaches, precipitates are represented by an interaction potential, completely …

Molecular dynamics simulations of dislocation/obstacle interactions are enhancing our
physical understanding of plasticity. However, despite increasing computational power, the …

Void strengthening in crystalline materials refers to the increase in yield stress due to the
impediment of dislocation motion by voids. Dislocation dynamics (DD) is a modeling method …

A relative contribution to irradiation hardening caused by dislocation loops and solute-rich
precipitates is established for RPV steels of WWER-440 and WWER-1000 reactors, based …

In this study, the atomic processes involving the interaction of an edge dislocation with
carbide precipitates in an iron matrix are investigated by molecular dynamics, utilizing two …

Abstract Amorphous Ni 53 Nb 20 Ti 10 Zr 8 Co 6 Ta 3 powders were successfully fabricated
by mechanical alloying. The glass-forming ability and crystallization behavior of the …

A series of large-scale molecular dynamics simulations were carried out to investigate the
interactions between an extended edge dislocation (1/2< 112>{111}) and nanoscale …

Abstract By exploiting Monte Carlo methodology and molecular dynamics, we
computationally simulate the spinodal decomposition of iron–chromium binary alloys and …
