Microstructure is closely related to properties of materials, and development of the latest materials through microstructure design is attracting many attentions. In order to optimize a microstructure, it is necessary to understand not only what the microstructure is composed of, but also how the microstructure is formed, that is, formation mechanism through phase transformations. For example, magnetic properties of permanent magnets mounted on traction motors and electronic devices are greatly influenced by the grain size of ferromagnetic phase, and phase transformations during the manufacturing process have a great impact on the microstructure formation. We are dedicated to studies on the microstructure of functional materials such as strong magnets by using advanced electron microscopy and intended to clarify the relationship between the material properties and the microstructures.
