Electromagnetic Materials Processing

In metallurgical processes, there are many possibilities of applying electromagnetic force or electromagnetic fields in order to overcome the difficulties in our conventional processes. In our research, we consider the application of the DC Lorentz force, the magnetization force and the strong magnetic field to be useful in the development of innovative processes and fundamental research in this area has been conducted for some years.

Deformation and Fatigue Mechanisms of HCP Metals

Deformation and fatigue mechanisms of HCP metals, such as titanium and magnesium, have not yet been clear. The aim of this research is to establish the mechanisms through experimentation using single crystals and computer simulation. Through the establishment of the mechanisms we can attain an effective development of the mechanical properties of HCP metals.

Fatigue Properties of Ultra-fine Grained Materials Fabricated
by Severe Plastic Deformation Process

UltraFine Grained (UFG) materials having ultrafine grain smaller than 1μm can be fabricated by the process of severe plastic deformation (SPD). This study has been carried out to clarify the fatigue properties of UFG materials. Fatigue strengths and lives of the accumulative roll bonding (ARB) processed sheet are higher than those of the starting sheet.

Grain Boundary Engineering for Developing Advanced Materials
with Excellent Function and Performance

Our group’s research is focused on the physical properties of grain boundaries and interfaces, the influence of grain boundary microstructure on the function and performance of polycrystalline materials and the development of processing methods to control the grain boundary microstructure.

Microstructural Control of Bonding Interfaces in Dissimilar Material Joints

Dissimilar material joints consisting of metals and ceramics are fabricated by various joining methods, such as explosive welding, diffusion bonding, brazing and soldering. Their interfacial microstructures and bonding characteristics are investigated in order to optimize bonding conditions and to gain information about chemical reactions and diffusion phenomena at the interface.
