Université Paris 13, France

Guy DIRRAS, PhD, is Professor of Materials Science, Physical and Structural Metallurgy at University Paris 13 (member of Sorbonne-Paris-Cité University Thrust ). His research activity is carried out at the Laboratory for Science, Materials and Processes (LSPM-CNRS). His scientific interests are interdisciplinary in nature and are intended to identify microstructural phenomena and elementary mechanisms that govern the mechanical behavior at macroscopic scale of metals and alloys (nanomaterials, thin films, intermetallic ...) and metal matrix nanocomposites. His traditional centers of interest include powder metallurgy processing; fine microstructural characterization (electron microscopy, X-ray diffraction), the study of the mechanical behavior and analysis of deformation mechanisms and fracture of metals and intermetallic alloys, the characterization of collective behavior and the arrangement of dislocations in the context of large deformation, the identification interaction mechanisms between different structural defects (dislocations, precipitates, grain boundaries ...). His current research topics are: (i) the engineering of architectured microstructures coupled with the identification of deformation mechanisms under quasi-static and dynamic deformations, (ii) micromechanical modeling and the coupling induced by nanostructuring and (3i) study of the relationships between microstructure – physical – mechanical properties of lignocellulosic (LCFs) materials used as nanocomposite reinforcements.
