About the Lab

Professor Young-Kook Lee's research lab specializes in the development and characterization of advanced high-manganese steels and Fe-Mn-based alloys, focusing on microstructure-property relationships. The lab investigates phase transformations, deformation mechanisms, and damping behavior in these materials, with particular emphasis on transformation-induced plasticity (TRIP) and the role of retained austenite (γR) in enhancing strength-ductility balance. Research directions include optimizing chemical composition and processing parameters to tailor microstructure and mechanical performance, especially in medium Mn steels and Fe-Mn binary alloys with high damping capacity. The lab also explores the fundamental mechanisms behind defect-mediated damping in multiphase Fe-Mn systems.

Current opinion in medium manganese steel
Young‐Kook Lee, Jeongho Han
SJR Q2Materials Science and Technology

Medium Mn steels have been actively investigated due to their excellent balance between material cost and mechanical properties. The steels possess a single α′ martensite phase in hot and cold rolled states and multiphases after intercritical annealing. Many studies have focused on investigating the influences of chemical composition and annealing conditions on the microstructure, particularly the grain size and retained γ (γ R ), and on the tensile properties. The steels exhibit high strength a
