Electron channelling contrast imaging of dislocations in a conventional SEM Dislocations in shock loaded tantalum single crystals were imaged using both TEM and ECCI in an SEM with a conventional backscattered electron detector. The results were compared with backscattered electron intensity profiles across dislocations calculated via the dynamic theory of electron diffraction. A one-toone correspondence between ECCI and TEM is established. High voltage and low index reflections should be used
