Neutrons and Xrays allow probing the dynamic behavior of microstructures through diffraction or 3D imaging and this over length- and time-scales commensurate of deformation and damage mechanisms at the mesoscale. Insitu deformation studies can provide therefore interesting synergies between experimental and computational material science. Coupling these two offers new means to elucidate long-standing critical questions and provide new mechanistic insight into the deformation and fracture of metals. With the upcoming free-electron lasers like SwissFEL, providing very intense and tightly focused beams of x-rays with pulses as short as 10 femtoseconds, the timescale of atomistic based computational methods can be reached, opening the pathway to a new generation of synergies.
Bio: Helena Van Swygenhoven studied physics in the Free University of Brussels and obtained 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 in Switzerland with a Marie-Heim Vögtlin stipendium from the Swiss National Science Foundation. She heads now at PSI a research group focussing on structural and mechanical properties of metals. With her group she designed a series of insitu methods at the Swiss Light Source and the Swiss Neutron Spallation Source allowing following the footprints of microstructures during deformation or thermal treatments. The strength and uniqueness of her research group lies in the synergies produced between these insitu methods and computational material science. She recently received an ERC advanced grant for studying deformation mechanism during insitu non-proportional multiaxial loading.
