Topic description
Cette recherche se concentrera sur la compréhension de la relation entre la microstructure des revêtements de Zn-Al-Mg et leur comportement mécanique dans différentes conditions de chargement. Le projet utilisera une approche multi-échelle, combinant des techniques expérimentales telles que les essais mécaniques, la microscopie (SEM, EBSD, et TEM), et des méthodes de caractérisation avancées pour caractériser l'évolution de la microstructure au cours de la déformation. Des simulations numériques seront systématiquement utilisées pour interpréter les résultats expérimentaux à l'échelle du grain en utilisant des simulations de plasticité cristalline combinées à la prévision de l'initiation et de la propagation des dommages. Le travail bénéficiera de l'étroite coopération entre ArcelorMittal OCAS et Mines Paris, ce qui permettra de comparer les propriétés mécaniques de plusieurs revêtements ayant des compositions chimiques différentes.

This research will focus on understanding the relationship between the microstructure of Zn-Al-Mg coatings and their mechanical behavior under different loading conditions. The project will employ a multi-scale approach, combining experimental techniques such as mechanical testing, microscopy (SEM, EBSD, and TEM), and advanced characterization methods to capture the microstructural evolution during deformation. Numerical simulations will be used systematically to interpret experimental results at the grain scale using crystal plasticity simulations combined with prediction of damage initiation and propagation. The work will benefit from previous close cooperation between OCAS and Mines Paris, allowing for a comparison of the mechanical properties of several coatings with different chemical compositions.
