| Research Abstract |
In order to understand the relationships between the property changes and the microstructural changes of functional composite materials due to additional element or annealing process, the structure was characterized by SEM, TEM and 3DAP with multi-scale. The origin of coercivity change by Dy diffusion process or low temperature annealing of Nd-Fe-B sintered magnet had been shown. And, the reason of ion conductivity deterioration of Gd doped CeO_2 was found to be related with grain boundary segregation and compositional fluctuation in the grain based on UV laser 3DAP analysis result.
