A multi-objective optimization to characterize the diffusion of nanocavities in tungsten

A. De Backer, A. Souidi, E.A. Hodille, Emmanuel Autissier et autres

We characterize the diffusion properties of nanocavities and their uncertainties by designing a multi-objective optimization approach. In this work, the nanocavity diffusion on the 0.3–4 nm size range is the input of a multi-scale simulation that is adjusted to reproduce experimental results …

Readdressing nanocavity diffusion in tungsten

Andrée De Backer, A. Souidi, E.A. Hodille, Emmanuel Autissier et autres

In nuclear fusion (ITER and the future DEMO), those components that face the plasma are exposed to high temperature and irradiation which, in the long term, modifies their thermal and mechanical properties and tritium retention. Tungsten is a candidate material and is …

Multi-Objective Optimization of the Nanocavities Diffusion in Irradiated Metals

A. De Backer, A. Souidi, E.A. Hodille, Emmanuel Autissier et autres

Materials in fission reactors or fusion tokamaks are exposed to neutron irradiation, which creates defects in the microstructure. With time, depending on the temperature, defects diffuse and form, among others, nanocavities, altering the material performance. The goal of this work is to …

Replacement collision and focuson sequences revisited by full molecular dynamics and its binary collision approximation

Charlotte Becquart, A. Souidi, M. Hou

In displacement cascades, a fraction (roughly one third) of the primary knock-on atom energy is partitioned between two types of linear events: focusons and replacement sequences. While replacement sequences lead to the formation of Frenkel pairs, focusons dissipate energy without creating any …

Relation between the interaction potential, replacement collision sequences, and collision cascade expansion in iron

Charlotte Becquart, A. Souidi, M. Hou

The binary collision approximation (BCA) grounded on molecular dynamics results is used to investigate the influence of the range and stiffness of interatomic potentials on the replacement collision sequence (RCS) length and frequency distributions as well as on the displacement cascade expansion …
