David Mayweg

Postdoctoral Research Associate at Chalmers University of Technology
After an undergraduate degree in mechanical engineering and some years of work as design engineer David returned to the university to obtain degrees in materials science and engineering (MSc at University of Siegen, PhD at RWTH Aachen University/Max-Planck-Institut für Eisenforschung, all in Germany). As a doctoral researcher he built a testing rig for bearing steels used electron microscopy and atom probe tomography (APT) for nm scale characterization of subsurface damage in bearing steels.
Since joining the division of microstructure physics at Chalmers in April of 2021 (funded by the Swedish Centre for Nuclear Technology - SKC) he focuses mostly on APT (sadly neglecting TEM) to characterize the microstructure of fuel cladding tubes from BWR operation.
One key interest has since be the analysis of hydrogen and hydrides, which is notoriously challenging in APT and made even more intricate by the effects of sample preparation. Noticeable progress has been made in the analysis of clustering at irradiation-induced a- and c-loops, secondary phase particle (SPP) dissolution and describing the nature of the oxide metal interface. As his time in the is drawing to a close, efforts are now concentrated on publishing the results of the last two years.
