ArcelorMittal is carrying out a research program aiming at determining the forming and mechanical properties of Zn-Al-Mg coatings on hot-dip galvanized steel sheets, depending on the solidification microstructures. The research strategy is developed along 5 lines: material selection, advanced characterization techniques, macroscopic mechanical properties of coatings, mesoscale modelling of microstructures and identification of deformation and inter- and transgranular damage mechanisms. The proposed PhD project aims at applying advanced characterization and modeling techniques for a better understanding of the mechanical properties of Zn-Al-Mg coating along the previous lines. The objective is to draw from these observations new guidelines for the microstructure optimization.

Multiscale modeling and simulation of wear resistant steels: • Study of a new methodology for multi-scale modeling. • Modeling of crystal plasticity. • Determining the level of damage. • Reconstruction of microstructures and texture analysis.
