Helena Van Swygenhoven, EPFL IMX, Paul Scherrer Institute, Villigen Bio : Helena Van Swygenhoven is Professor in IMX/STI/EPFL and a senior research staff member and group leader at the Paul Scherrer Institute, Switzerland. She studied physics in the Free University of Brussels and received her PhD degree in physics from the Central Jury in Belgium on radiation damage in materials. After a professional break for motherhood, she joined the Fusion Technology Division at the Paul Scherrer Institute with a Marie-Heim Vögtlin stipendium from the Swiss National Science Foundation. She moved to the Neutron Spallation Source department and started a research group focusing on the mechanical bahaviour of metallic microstructures. The group is internationally known for the development of synergies between computational material science and in-situ experiments with Xrays and neutrons. |

Abstract : The microstructure of today’s metals is steadily increasing in complexity because of the increasing demands in performance. To develop improved predictive computational models one needs characterization and testing methods that can follow the dynamics of these microstructures to validate computational models and/or can provide input parameters for new models.
Recent advances in X-ray and neutron technologies at large facilities have brought increased beam intensities, improved detector efficiencies and sub-micron focusing techniques. In-situ mechanical testing during X-ray and neutron diffraction has become an excellent research method to follow the dynamics of microstructures under load. In-situ experiments provide information on elastic and plastic anisotropy, load-sharing, strengthening and phase transforming mechanisms, or degradation phenomena. These methods are therefore excellent tools to develop synergies with computational modeling.
In this seminar the basics of insitu mechanical testing will be explained and illustrated with research performed at the Swiss Light Source (SLS) and the Swiss Neutron Spallation source (SINQ) at the Paul Scherrer Institute.
