Dr. Alice Perrin joined ORNL in 2021 as a Weinberg Distinguished Staff Fellow. Alice's fellowship research is focused on studying the effects of ion irradiation on solute behavior in grain boundary segregating nanocrystalline alloys. She is part of the Microstructural Evolution Modeling Group in the Materials Science and Technology Division of the Physical Sciences Directorate. Her general research interests revolve around phase stability of novel metallic alloys, nonequilibrium processing and how it intersects with thermodynamic and kinetic stabilization of metallic microstructures, functional alloy design, and additive manufacturing. She is currently involved in projects focused on characterization of refractory alloys designed for additive manufacturing, identification of equilibrium and metastable phases in Al-based alloys, and development of bulk amorphous Al alloys. She was previously a postdoctoral researcher at the Massachusetts Institute of Technology (2019-2021) and worked on developing rapid sintering Ni-based alloys. She has been an associate editor for the Journal of Materials Research since 2021.
Alice earned her Ph.D. in Materials Science and Engineering from Carnegie Mellon University in 2019; she obtained her M.S. in Materials Science in passing from Carnegie Mellon University in 2017, and her B.S. in Physics from The College of William and Mary in 2015. Her Ph.D. dissertation, "Characterization of High Entropy Alloys for Magnetocaloric Applications", explored the complex magnetic and thermal properties of FeCoNiCuMn high entropy alloys (HEAs), the first HEAs with room temperature magnetic transition temperatures, which were a proof of concept that the operating temperature ranges of magnetocaloric alloys can be shifted and broadened through careful tuning of distributed magnetic exchange interactions.
