Development of new metallic glass alloys and elucidation of their functions

Metallic glasses (metallic alloys that exhibit a glassy state) exhibit properties such as strength, corrosion resistance, and soft magnetic properties that differ from those of metallic alloys with a crystalline structure, and they can be formed in complex ways. We will develop new materials with excellent environmental resistance by studying the mechanism of metallic glass formation.

Introduction to Research

Developed a candidate catalyst material for low-cost, high-efficiency hydrogen generation without precious metals. Realization of 3D nanostructuring of intermetallic compounds, which are brittle, hard to dissolve, and difficult to process. Successfully achieved both high strength and high ductility in high entropy alloys using half metals.

Objective

We will work to unravel the mysteries of glass formation in metallic glasses, develop new metallic glass alloys with superior properties, and promote their application to functional metallic glass materials.
