Microstructure is strongly related to properties of materials. Novel functional materials have been developed based on microstructure-based engineering, where understanding of optimal design of microstructure and mechanism of microstructure formation such as phase transformations is important. For example, magnetic properties of permanent magnets that contributes to developments of different electric devices are related with grain size distribution of magnetic phase and dispersion state of non-magnetic phase, and phase transformation in heat-treatments plays a key role for optimizing microstructures. In our research, microstructure and its formation mechanism are extensively studied with the latest electron microscopes.
