3D electron tomography reconstructions of dislocations in TiAl

, 2023
These movies show 3D electron tomography reconstructions of dislocations formed in TiAl at 800-900°C. They were acquired in samples deformed at 900°C by 2% (Movie 1) and by 20% (Movies 2, 3 and 4) of plastic deformation, and in a sample deformed at 800°C
