Electron Backscatter Diffraction (EBSD) is a scanning electron microscope (SEM) based technique that gives crystallographic information about the microstructure of a sample. In EBSD, a stationary electron beam interacts with a tilted crystalline sample and the diffracted electrons form a pattern that can be detected with a fluorescent screen. The diffraction pattern is characteristic of the crystal structure and orientation in the sample region where it was generated. Hence the diffraction pattern can be used to determine the crystal orientation, discriminate between crystallographically different phases, characterise grain boundaries, and provide information about the local crystalline perfection.
EBSD has become a well-established accessory for the SEM, which is used to provide crystallographic information routinely. As a result, EBSD is now being applied in numerous different application areas to assist in materials characterisation, as shown by the table below.
The AZtec EBSD system combines the speed and sensitivity of the world's fastest and most sensitive EBSD detector, Symmetry, with the superior analytical performance of AZtecHKL software to create a powerful and versatile tool for Electron Backscatter Diffraction (EBSD) and Transmission Kikuchi Diffraction (TKD) analysis.
