Revisiting quantum effects on dislocation glide in bcc metals from DFT calculations and machine-learning potentials
Arnaud Allera, Lisa Ventelon, Mihai-Cosmin Marinica +2
Quantum zero-point effects have been long proposed to explain a well-known discrepancy between the low-temperature flow stresses of body-centered cubic metals and corresponding ato…
Mobility of screw dislocation in BCC tungsten at high temperature in presence of carbon
Guillaume Hachet, Daniel Caillard, Lisa Ventelon +1
The interplay of screw dislocations with carbon atoms is investigated in tungsten at high temperature using in situ straining experiments in a transmission electron microscope (TEM…
Screw dislocation-carbon interaction in BCC tungsten: an ab initio study
Guillaume Hachet, Lisa Ventelon, François Willaime +1
The interaction between carbon and screw dislocations in tungsten is investigated using ab initio calculations. The presence of carbon atoms in the vicinity of the dislocation indu…
Assessment of interatomic potentials for atomistic analysis of static and dynamic properties of screw dislocations in W
David Cereceda, J. Manuel Perlado, Alexander Stukowski +4
Screw dislocations in bcc metals display non-planar cores at zero temperature which result in high lattice friction and thermally activated strain rate behavior. In bcc W, electron…
Dislocation core field. II. Screw dislocation in iron
Emmanuel Clouet, Lisa Ventelon, F. Willaime
The dislocation core field, which comes in addition to the Volterra elastic field, is studied for the <111> screw dislocation in alpha-iron. This core field, evidenced and characte…
Dislocation Core Energies and Core Fields from First Principles
Emmanuel Clouet, Lisa Ventelon, François Willaime
Ab initio calculations in bcc iron show that a <111> screw dislocation induces a short-range dilatation field in addition to the Volterra elastic field. This core field is modeled…
