Webinar Description
In this seminar, Dr. Gregory B. Thompson from The University of Alabama delved into the benefits of correlative Transmission Electron Microscopy (TEM) and Atom Probe Tomography (APT) for studying structure-chemical relationships in nanocrystalline metals.

The talk covered how combining TEM and APT helps explain solute segregation in metals. Dr. Thompson demonstrated how precession electron diffraction can identify grain boundary types, which, together with atomistic simulations, can validate solute segregation tendencies. Additionally, in situ annealing experiments were discussed in terms of boundary faceting evolution.
Discussion highlights:
- Grain Boundary Segregation: Insight into solute segregation tendencies in metals, using precession electron diffraction.
- TEM in Action: High-resolution TEM’s role in observing boundary evolution during annealing.
- TEM-APT for Defects: Correlative microscopy’s use in studying chemical defects and their influence on phase separation in nanocrystalline metals.
