Advanced Microstructure Control for Developing New Structural Metallic Materials

Steel is the most important and fundamental material to support our society at present and in future. We attempt to control mechanical properties of structural metallic materials through design of microstructure 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 inhomogeneity in an atomic scale (e.g.segregation at phase boundary) and so on. Fundamentals of microstructure formation (thermodynamics, kinetics, crystallography) are examined in detail to clarify key factors for microstructure control to improve mechanical properties.
