Evolutions Microstructurales : Observation Directe à l'Echelle Atomique grâce à la Sonde Atomique Tomographique

Last year, we presented a contribution to illustrate the increasing role of Atom Probe techniques in the study of solid state phase transformations in metallic materials [1]. We concluded this paper with a mention to the emergence of a new generation of atom probes, giving access to quantitative 3D images on the sub-nanometric scale. In this paper, we will present the instrument of this new generation developed at the Université de Rouen, as well as some of the most interesting results we could obtain since it started to operate last year
