The roles of structural materials are keeping the shape and functions of structural objects such as buildings, railways, ships and cars, and defending our security during the use of them. To fulfill the roles, structural materials are required to enhance various kinds of mechanical properties: For example, car bodies need high strength as well as good ductility because they must have a sufficient collision safety to save the life of drivers and a good formability for designing complicated shape. Steel plates and bars for ships and buildings need high toughness to bear impact shocks or earthquakes. Flying objects such as air planes and rockets require light weight and tough properties. For medical apparatus, not only strength but also flexibility are desired. Such properties of structural materials are closely related with their metallic microstructure, and we can draw the performance potential of the materials by controlling their microstructure. We aim to fabricate new materials contributing to future technologies by controlling and analyzing the structure of metallic materials in micro- and nano-scale. And we hope to develop high strength steel sheets with excellent deformability, structural steel plates with high toughness even at cryogenic temperature, light and strong titanium alloys, high strength stainless steels with excellent corrosion resistance and oxidation resistance, human friendly metallic materials, and so on.
