Areas interesting to interact with
Ti alloys, Development of parts for aircrafts, Development of high temperature resistant materials, Development of structural parts for transports, Development of thermoelectric materials and improvement in plastic deformability
Development of light weight plates, Develoment of high strength and temperature resistant Mg alloys and Development of special container
Using analytical electron microscopy including transmission electron microscopy, we have suceeded in development of new alloys, improvement in mechanical properties, obtaining high strength based on age-hardening treatments, evaluation and development of high temperature resistant materials and elucidation of effects of alloying elements on properties in light metals such as Al, Mg and Ti alloys. By applying the knowledge of the structural materials. improvement efficiency of thermoelectric materials has also been conducted. In addition, we also try to understand deformation mechanisms of ice in polar regions based on knowledge of them in metalic materials.
