The current magnetic confinement nuclear fusion power reactor concepts going beyond
ITER are based on assumptions about the availability of materials with extreme mechanical …

Dislocation cores, the regions in the immediate vicinity of dislocation lines, control a number
of properties such as dislocation mobility, cross-slip and short-range interactions with other …

We have developed empirical interatomic potentials for studying radiation defects and
dislocations in tungsten. The potentials use the embedded atom method formalism and are …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

The low-temperature plastic yield of α-Fe single crystals is known to display a strong
temperature dependence and to be controlled by the thermally activated motion of screw …

This review paper focuses on dislocations and plastic deformation in magnesium oxide
crystals. MgO is an archetype ionic ceramic with refractory properties which is of interest in …

In the traditional picture of plasticity in bcc metals, edge dislocations have been assumed to
play a minor role due to their high mobility with respect to screw dislocations, which then …

Density functional theory models developed over the past decade provide unique
information about the structure of nanoscale defects produced by irradiation and about the …

The atomistic study of kink pairs on screw dislocations in body-centered cubic (bcc) metals is
challenging because interatomic potentials in bcc metals still lack accuracy and kink pairs …

Abstract Thermally-activated 1/2< 111> screw dislocation motion is the controlling plastic
mechanism at low temperatures in body-centered cubic (bcc) crystals. Dislocation motion …
