ArcelorMittal a entrepris depuis un certain nombre d\u2019ann\u00e9es, en collaboration avec J.B. Leblond et J.M. Bergheau, de simuler num\u00e9riquement certains traitements m\u00e9tallurgiques des aciers qui en provoquent l\u2019oxydation interne (combinaison, en profondeur, d\u2019atomes d\u2019oxyg\u00e8ne en provenance de la surface avec certains atomes d\u2019\u00e9l\u00e9ments d\u2019alliage, conduisant \u00e0 la formation de pr\u00e9cipit\u00e9s d\u2019oxydes). Les ph\u00e9nom\u00e8nes, qui impliquent des effets fortement coupl\u00e9s de diffusion d\u2019\u00e9l\u00e9ments chimiques et de r\u00e9actions entre ces \u00e9l\u00e9ments, sont d\u00e9crits par des \u00e9quations diff\u00e9rentielles aux d\u00e9riv\u00e9es partielles tr\u00e8s non
\n-lin\u00e9aires, dont la r\u00e9solution num\u00e9rique pose des difficult\u00e9s sp\u00e9cifiques et consid\u00e9rables. Les travaux effectu\u00e9s, qui ne semblent pas avoir d\u2019\u00e9quivalents dans le monde, ont permis de r\u00e9soudre beaucoup de difficult\u00e9s et de r\u00e9soudre des probl\u00e8mes d\u2019int\u00e9r\u00eat pratique consid\u00e9rable.<\/p>\n
