Research Abstract

Electron tomography based on transmission electron microscopy has been developed for study of 3-dimensional morphology due to ordering and phase separation in crystalline alloys, and it has been applied to formation and time-evolution of two-phase morphology in Fe-Al-Ni and Ni-Al-Ti ordering alloys. This method enables us to discuss the time-evolution of phase separation in terms of temporal change in volume fraction of the two phases, and to analyze local atomic composition in an embedded second phase in the matrix phase.
