Advanced microstructure control for developing new structural metallic materials

Steels are most important and fundamental material to support lives and industries at present and in the future. We attempt to control mechanical properties of metallic structural materials through microstructure control and to clarify principles of microstructure evolution by means of advanced experimental and theoretical techniques.

We focus on advanced control of micro/nanostructures, such as atomic structures of crystalline interfaces, chemistry in an atomic scale (e.g., segregation) and so on. Fundamentals of microstructure formation (thermodynamics, kinetics, crystallography) are examined both theoretically and experimentally to clarify key factors for microstructure control to improve mechanical properties.
