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…
Atomic-scale avalanche along a dislocation in a random alloy
Sylvain Patinet, Daniel Bonamy, L Proville
The propagation of dislocations in random crystals is evidenced to be governed by atomic-scale avalanches whose the extension in space and the time intermittency characterizingly d…
Hydrogen and vacancy clustering in zirconium
Céline Varvenne, Olivier Mackain, Laurent Proville +1
The effect of solute hydrogen on the stability of vacancy clusters in hexagonal closed packed zirconium is investigated with an ab initio approach, including contributions of H vib…
Quantum Peierls stress of straight and kinked dislocations and effect of non-glide stresses
B. Barvinschi, L. Proville, D. Rodney
It was recently shown that to predict reliable Peierls stresses from atomistic simulations, one has to correct the Peierls barrier by the zero-point energy difference between the i…
Pressure Fronts in 1D Damped Nonlinear Lattices
S. Aubry, L. Proville
The propagation of pressure fronts (impact solutions) in 1D chains of atoms coupled by anharmonic potentials between nearest neighbor and submitted to damping forces preserving uni…
Depinning of a discrete elastic string from a two dimensional random array of weak pinning points
Laurent Proville
The present work is essentially concerned with the development of statistical theory for the low temperature dislocation glide in concentrated solid solutions where atom-sized obst…
