About

Kim Hye-Jin is an Assistant Professor at Tech University of Korea. Her research focuses on hydrogen embrittlement mechanisms in advanced steels, particularly in the context of quenching and partitioning (Q&P) steels and medium-Mn steels. Recent publications include studies on hydrogen-assisted mechanical degradation, hydrogen diffusion behaviors, and the effects of pre-strain on the plasticity and fracture characteristics of various steel types.
