Research

Focusing on metallic materials, such as steels, titanium, and amorphous alloys, my study is to develop or improve mechanical and functional properties of them through a microstructure control using deformation and heat treatment techniques. Moreover, in order to reveal the mechanism of newly found mechanical and/or functional properties, I am engaging in the study about 'kinetics analysis', which precisely investigates time, temperature, and stress dependence of deformation or reaction.
