Advanced Components and Materials have been widely used in automotive, vessel and aircraft, as well as electronic appliances in real life. In order to develop products which have outstanding workability, formability, and electrical properties, it is essential to understand physical properties and micromechanical behaviors in Advanced Components and Materials. In recent years, a variety of studies using multiscale modeling have been conducted to improve performances of Advanced Components and Materials. Our laboratory is intensively conducting researches on microstructure characterization and multiscale modeling covering from nanoscale to macroscale for microstructure control and processing optimization in Advanced Components and Materials.
