Corrosion Resistant Alloy Group

Our group aims to clarify and understand the role of rare metal elements in phase stability and mechanical properties using various advanced analytical tools. It is the mission to develop advanced structural materials, such as steels, titanium alloys, magnesium alloys and aluminum alloys, and functional materials such as shape memory alloys, damping alloys, by designing and controlling the heterogeneous structures from nano to micron scale.

Specialized Research Field
