In this work, a degenerate diffusion state is identified for common L12 intermetallics in well-
defined five-frequency model (FFM) and anti-site bridge model (ASB). The relative energy …

The equilibrium vacancy concentration and atomic diffusion coefficients in dilute and
complex refractory alloys have been calculated using various computational methods. The …

This work investigates the interplay between thermal vacancy and short-range order (SRO)
in complex concentrated alloys (CCAs) for the purposes of accurately predicting SRO …

Compared to face-centered cubic (fcc) high-entropy alloys (HEAs), body-centered cubic
(bcc) HEAs generally possess larger lattice distortion, resulting in distinct point defect …

Estimating tracer and intrinsic diffusion coefficients following the diffusion couple method
with systematic composition variation can be challenging because of the diffusion paths' …

Mes principales recherches portent sur les propriétés des défauts dans les systèmes de
métaux de transition (en particulier Fe) d'intérêt pour l'énergie nucléaire. L'objectif est de …

Vacancies play crucial roles in various phase transformation processes in metallic solids,
but their diffusion behaviors in the presence of solute elements are less known. In this work …
