Research interests
Prof. Han’s primary research interests are the mechanical behavior of metallic structural materials, irradiation effects, and design of high performance advanced structural materials for extreme environments. He has made contributions including proposing the concept of dislocation source efficiency, discovering that the relative mobility of screw versus edge dislocations as a dominant factor governs the ductile-to-brittle transition in body-centered cubic metals, elucidating the critical roles of point-defect complexes on anomalous irradiation hardening and oxygen/helium/hydrogen embrittlement, and revealing interface-mediated mechanisms for tuning the strength-toughness balance and irradiation resistance in metallic materials.
