About

Williams Lefebvre Ulrikson is a Professor at the University of Rouen, France. His research focuses on the mechanical properties and microstructural characteristics of alloys, particularly Ni20Cr and Inconel 718, in the context of additive manufacturing and laser powder bed fusion processes. Notable recent publications include studies on the formation mechanisms of core-shell oxides, the impact of processing on material properties, and advanced characterization techniques using atom probe tomography.
