Our research interest

Materials Science via Electron Tomography:
It is one of key points in understanding the origin of material properties to determine microscale and nanoscale structures. For this purpose, transmission electron microscopy (TEM) is widely used, which enables to analyze internal structure of materials with high spatial resolution.
However, structural information that we can obtain from ordinary TEM is confined to two-dimensional one that is projected to a particular direction, which is against that real material possesses three-dimensional structure.
In order to truly understand structure-property relationship, we study structure of materials with the use of electron tomography, which allows us to determine three-dimensional structure with the spatial resolution of several nano meters.



Microstructural analysis of steel:
Steel is widely used in various kinds of practical applications. In most of the cases, steels are required to be hard enough and not to break so easily. For this purpose, materials are often designed to possess the microstructure where fine particles of other materials are dispersed throughout.
We are studying microstructure of steels to understand how such fine particles are distributed within the material and how the steels are strengthened. By doing so, we try to find the method to obtain hardest steel ever.

Microstructural analysis of aluminum alloys:
Since aluminum alloy is lighter and harder, it is used, for example, in the body of automobile. In order to make harder aluminum alloy, we need to tailor the microscale and the nanoscale structures.
We are studying micro- and nano-structure of the alloys to understand microstructural evolution and the dependence on fabrication condition.



Materials processing of superconductors:
Since superconducting materials exhibit zero electrical resistance and expulsion of magnetic fields, they are intensively studied for the application to non-loss electric lines and magnetic levitation train, and so on.
In order to obtain superconducting materials with higher performance, e.g., higher critical current, higher critical tempearture, and so forth, we are studying optimal material process of these materials. In particular, our attention is focused on artificial pinning center and its distributioin within the material, which effectively enhances critical current when superconductors are used in magnetic field.



Microstructural analysis of ceramic materials:
