Masakazu Tane, Professor
0 student voices
The Materials Informatics Lab (Tane Lab) studies the mechanics, phase transitions, and microstructure formation of materials. The lab regards materials as hierarchical, complex mechanical systems spanning the nanoscale to the macroscale, and investigates them using mechanics, such as mechanics of materials and thermodynamics, together with multiple regression analysis. The lab also works on developing measurement and analysis systems. The lab hopes that students who join it will, through their research, combine experimental science and computational science and grow into professionals who will lead this interdisciplinary field.

The Materials Ultrafine Process Engineering Lab analyzes the relationship between ultrafine structures and material properties at nanometer spatial scales and nanosecond time scales. Using the latest transmission electron microscopy, electron diffraction, and electron and X-ray spectroscopy, the lab investigates inhomogeneities in materials, typified by crystal lattice defects. Based on the results of these analyses, the lab advances materials design. The lab conducts education and research aimed at elucidating universal, common principles that lie at the foundation of materials science.
Mitsuru Ohata, Professor

The Materials Structural Integrity Evaluation Lab (Ohata Lab) studies the mechanisms by which large structural members, such as steel for buildings, bridges, and other infrastructure structures, fracture. Guided by the philosophy of "knowing how things break, to research how to keep them from breaking," the lab works to build the foundations of fracture evaluation technology and to develop theory and simulation technology that lead to the design of new materials and joints. By linking different hierarchical levels, from the performance of structural members to the properties of materials, the lab approaches the mechanisms of fracture.
Takeshi Yoshikawa, Professor

The Yoshikawa Lab (Materials Thermodynamics) studies new manufacturing processes for next-generation materials, built on thermodynamics, kinetics, and crystal growth engineering. The lab develops its own observation techniques to directly "see" high-temperature reactions, phase transformations, and crystal growth, and controls processes based on an understanding of these phenomena. Its targets include SiC, nitride semiconductors, metallic materials, and recycling processes. The lab also works toward zero-emission manufacturing of steel, nonferrous metals, glass, and ceramics, and on environmental materials that make up for the CO₂ emitted to date.
Takayoshi Nakano, Professor
0 student voices
The Nakano Lab, based on materials science such as crystallography and crystal plasticity, studies the properties and functions of biological tissues. Using that knowledge, the lab aims to create innovative biomaterials and aerospace materials. Learning from the anisotropic arrangements and structures that biological tissues have at each hierarchical level, the lab uses metal 3D printers and computer simulation to create materials that perform well even in extreme environments. On the lab's website, it is introduced as the "Nakano Lab."
Yuichiro Koizumi, Professor

The Materials Design and Process Engineering Lab studies materials that deliver the desired performance and how to make them, combining computer simulation with experiments. Currently, the lab focuses on the solidification of metals that occurs in metal 3D printing (additive manufacturing), and works on controlling crystal orientation and size so that not only the shape but also the properties of the material are made as intended. The lab also works on metamaterials, which exhibit properties that the substance does not originally have through the shapes given by 3D printing, and on research that contributes to sustainable development, such as recycling. On the lab's website, it is introduced as the "Koizumi Lab."
Hiroshi Utsunomiya, Professor
0 student voices
The Materials Morphology Control Lab studies how to shape materials such as metals through metal forming, including rolling, forging, and extrusion. The lab proposes and develops processing methods for creating the new materials needed in the next generation, such as lightweight eco-materials, highly workable materials, and ultrafine-grained materials. At the same time, it is clarifying how a material's microstructure and properties are determined during processing, and developing methods to predict them. The lab's website introduces it under the name "Utsunomiya Lab."
Hiroaki Tsuchiya, Professor
0 student voices
The Tsuchiya Lab studies the processes by which metallic materials corrode and oxidize in aqueous solutions and high-temperature environments, and develops materials that withstand such environments. Using electrochemistry, surface analysis instruments, and computational science, the lab investigates how material surfaces function in terms of electronic structure, optical properties, and biocompatibility. The lab also works on creating structure-controlled material surfaces by controlling the interaction between materials and their environments through electrochemical processes.
Tomo Ogura, Professor

The Welding and Joining Process Engineering Lab studies how to control microstructure formation and reactions at joint interfaces, based on dissimilar material joining technology that joins different materials with high precision. Multi-material technology, which combines multiple materials where each suits best, is described as a technology that makes automobiles and transport equipment lighter and higher-performing and contributes to a carbon-neutral society. Based on joining metallurgy, which integrates metallurgical engineering and welding engineering, the lab covers everything from the design of joining processes to the prediction of joint interface properties. By making previously difficult material combinations possible, the lab aims to realize advanced manufacturing that combines light weight, high strength, and high functionality.
Kazuhiro Ito, Professor

The Welding and Joining Functional Design Lab studies what determines the functions and mechanical properties of joints formed by fusion welding and by liquid-phase and solid-state joining. The lab examines the microstructure of joints using electron microscopy and X-ray diffraction, and carries out modeling and simulation based on the results. Its goals are to build the foundations of materials design for producing defect-free joints with excellent functionality, to develop new joining methods, and to evaluate the properties of joined structures. On the website of the Joining and Welding Research Institute, the lab is introduced under the name "Welding Mechanism Field."
