Many of functional materials, such as semiconductor, solar cell and shape memory alloys, contains numerous interfaces and domains. Functional properties are greatly affected by the interfaces and boundaries between domains. We therefore focus on the “Interface Dynamics”, such as interface reaction and interface movement to develop the functional materials by means of collaborating materials design technology by microstructural control of Kumamoto university and interface evaluation technology of University of Vienna. We have clarified the microstructure and crystallography of martensite variants in TiPt high-temperature shape memory alloys induced by high pressure torsion and Zr-Co-Pd alloys. These obtained results and discussion are very useful to understand martensitic transformation, leading to improve the shape memory characteristics. We have also developed the new oxide films with visible light absorption by controlling the oxidation process of metals.
