Yoshikawa Laboratory　

To develop “Metallurgy for future society”, we conduct educational and research programs on comprehension and control of phenomena and properties of interfaces including high temperature melt, and creation of novel material processes based on the interfacial properties. Our research focuses on clarification of dynamic interfacial phenomena in materials production process (e.g. iron and steelmaking) by high temperature in-situ observations from macroscopic to atomic scales. Besides, we focus on evaluating physical properties such as interphase wetting phenomena and its applications, creation of functional materials by hydrothermal reaction utilizing byproducts of steelmaking process and waste heat, and fabrication of thermo-electric modules for utilization of waste heat.
