Carburization of Steels in High-Temperature, High-Pressure Supercritical CO2 environment
Kelly Nygren

Kelly Nygren is a postdoctoral research associate in the department of Engineering Physics at the University of Wisconsin-Madison (WI, USA). She received her PhD from the University of Illinois at Urbana-Champaign in Materials Science and Engineering. She is interested in materials characterization in extreme environments, with an emphasis on bridging microscale mechanisms with macroscale properties. Her dissertation focused on understanding the role of hydrogen on degrading fatigue properties and fatigue crack growth mechanisms in stainless steels through observing the evolved microstructure beneath fracture surfaces. She is currently working on characterizing the microstructures of ion irradiated Zr-alloys, steel subjected to supercritical-CO2, and high-entropy refractory alloys using techniques including transmission electron microscopy, focused ion beam machining, and atom probe tomography.
