This laboratory is engaged in the research of the development of advanced functional materials, metallic glasses, metallic-glass-matrix composites and nanoporous materials, which have remarkably different structure from those of conventional metals, by employing various nonequilibrium processes. The unique structure of such nonequilibrium material is expected to add novel functions to the material. Metallic glass is a glassy solid mainly prepared by rapidly quenching its liquid state. Due to its none-crystalline structure, metallic glass exhibits superior mechanical, chemical and magnetic properties. Metallic glass can transform to the supercooled liquid well below the melting temperature of its crystalline counterpart. This allows high precision viscous flow forming as the well-known ”glass working”. Based on the strategy of alloy design for metallic glass formation, we developed new dealloying method for fabrication of nanoporous metal and study its fundamental and application.
