| Outline of Final Research Achievements |
This project developed new methods or three-dimensional (3D) transmission electron microscopy (TEM) imaging for nanoscale microstructural features in crystalline materials. For example, a newly developed triaxial specimen holder system enables to visualize the 3D geometrical arrangement of dislocations (line-shape structural defects in crystalline grains) in a polycrystalline sample. A method for acquiring a tilt-series dataset from ferromagnetic samples (e.g. ferritic steels) in both TEM and STEM modes was also established.
