Metal components used in a wide range of products essential to our daily lives, such as smartphones, automobiles, and aircraft, are often manufactured by utilizing plasticity—the ability of metals to deform under applied force.

In this study, we develop novel processing methods that control the forces applied to materials during deformation at room temperature, thereby tailoring their internal microstructures. This approach enables not only the precise fabrication of components with designed geometries, but also the simultaneous control of their mechanical properties and functionalities, leading to higher-performance materials.

In parallel, we investigate the underlying mechanisms through advanced characterization techniques and numerical simulations.

The technologies developed in this study are applicable to a wide range of fields, contributing, for example, to improved image stabilization in smartphone cameras, further weight reduction in automobiles, and enhanced fuel efficiency in aircraft.
