Automotive Steels
1. Ultra high-strength steels design
2. Lightweight steels design
We design novel automotive steels based on Fe-Mn-Al-C system in order to obtain excellent a combination of strength-ductility.
Main strategies are to investigate nano- & micron-scale phase transformation & precipitation behaviors and to correlate them with mechanical properties.
We are focusing on the development of medium- and high-Mn steels and lightweight steels.


3. Hot-press forming steel design
We study ultra high-strength martensitic steels, Hot Press Forming (HPF) steels, used for the structural pillar parts in the automotive body.
Our interests are to control micro-alloying elements for precipitation & grain refinement and to investigate tensile, bending, impact, and delayed fracture properties.
