Krogstad is an assistant professor in the Depar tment of Material Science and Engineering at the University of Illinois\, Urbana-Champaign.\n\n\nKrogstad's current research explores the interpla y between phase or morphological evolution and material functionality in structural materials under extreme conditions. She is the recipient of th e DOE Early Career Award\, the NSF CAREER Award\, the ACerS Robert L. Cob le Award for Young Scholars and the TMS Early Career Faculty Fellow Award .\n\n\nAbstract:Point defects are ubiquitous within materials. In many ca ses these defects contribute to useful material functionality but in exce ss they can also lead to degradation. Here we present several vignettes i n which concentrated populations of point defects interact with microstru ctural features resulting in new perspectives on phase transformations an d diffusion kinetics. We will approach this discussion from two angles: m aterial systems wherein the excessive point defect population predominant ly arises through materials synthesis choices and the other in which poin t defects are introduced via bombardment of an already crystalline system . In the former\, the evolution of defects are driven by both intrinsic m aterials properties such as the stacking fault energy and extrinsic param eters such as substrate temperature and plasma energy. In the later\, the crystalline lattice must respond and adapt to the flux of defects. Howev er\, in both cases\, when the resulting nonequilibrium materials are allo wed to relax\, they do so in unexpected ways. We will present these obser vation as well as the broader potential of nonequilibrium point defect po pulations in understanding microstructural evolution\, mass transport and material functionality.\n\n\n\n\n\nThis seminar will be held exclusively on Zoom (955 5209 1021).
