Deformation Processes in TRIP/TWIP Steels

Anja Weidner is a scientific staff member at the Institute of Materials Engineering at the Technische Universität Bergakademie Freiberg, Germany, where she studied materials science, and earned both doctorate and postdoctorate qualifications. Her primary research interests focus on plasticity, fatigue and related microstructural analysis of materials. Since 2011 she has been working as a team leader for the group "Microstructural Analysis and Very High-Cycle Fatigue". Additionally, she is a board member of two Collaborative Research Centres: SFB 799 "TRIP-Matrix-Composites" and SFB 920 "Multifunctional Filter and Filter Systems", both funded by the German Research Foundation (DFG). Since 2013 she has been acting as coordinator of the research group "In-situ Testing in Scanning Electron Microscopy" within in the framework of the German Society for Materials Science. To date she has authored or co-authored over 94 peer-reviewed publications and has an h-index of 21.
