Biography

Charbel Moussa is a researcher specializing in the study of the microstructural mechanisms of metallic materials, with particular expertise in the analysis of aluminum alloys, nickel-based superalloys, and pure metals such as tantalum. His work focuses on the phenomena of precipitation, plastic deformation, dynamic and post-dynamic recrystallization, as well as the evolution of dislocations and crystalline substructures. Using advanced characterization techniques such as transmission electron microscopy (TEM), electron backscatter diffraction (EBSD), and dark-field X-ray microscopy (DFXM), he explores the interactions between precipitates, dislocations, and grain boundaries to understand their impact on the mechanical properties of materials. His research also addresses multiscale modeling, ranging from mean-field approaches to full-field simulations, to predict microstructural changes during thermomechanical treatments or industrial processes such as rolling or forming.
