Greeting

This laboratory's research consists in using various non-equilibrium fabrication processes to elaborate advanced functional materials such as metallic glasses, metallic glass matrix composites and nanoporous materials. These innovative materials display remarkably different structures from those of conventional metals, and exhibit outstanding properties, useful for the development of new innovative functional materials. Metallic glasses are glassy solid prepared by rapidly quenching their liquid state. Due to their none-crystalline structure, these materials exhibit outstanding mechanical, chemical and magnetic properties. Upon heating, metallic glasses also exhibit properties of supercooled viscous liquids at temperatures well below the melting temperature of their crystalline counterpart. This allows high precision viscous flow forming techniques (e.g. "glass working"). Based on a similar strategy than for metallic glass design, we have also developed a new dealloying method to fabricate nanoporous metals with outstanding properties.

For students

Graduate school of Engineering/Department of Metallurgy, Materials Acience and Materials Processing/Materials Science/Collaborative Research Groups [Non-Equilibrium Materials]

This laboratory is engaged in the research and development of new metallic glasses and their composites, exhibiting superior workability properties. To achieve this goal, we are interested in the fundamental understanding of these materials supercooled liquid states, their nanocrystallization process and stress relaxation mechanisms. Also, based on the originally developed liquid metal dealloying, we study the preparation of novel nanoporous materials and their applications for functional materials. Students are required to undergo the admission exam of the graduate school of Engineering.

Graduate school of Biomedical Engineering/Medical Materials [Designing Metal for Medicine Based on Metallurgy] 

The structure and morphology of metals can be designed to develop new materials for medical applications with high biocompatibility and excellent biological function.
1. Metallic phases are controlled to be the non-equilibrium states such as glassy and nano-crystalline phases by mean of the non-equilibrium process.
2. Using the dealloying technique, toxic elements can be removed from the surface body of metallic alloys to improve the biocompatibility properties of the resulting material.
Students are required to undergo the admission exam of the graduate school of Biomedical Engineering.

Research Students

The application for research student requires a bachelor's degree, master's or doctoral degree. Students should consult their home university to determine whether their exchange agreements exempt tuition.
