NIST Structural Database Used for Phase Identification in Electron Diffraction Instruments

Abstract
Researchers use crystallographic information on a daily basis to visualize, explain, and predict the behavior of chemicals and materials. The NIST structural Database (NSD) contains crystallographic and atomic positional information for metallic crystalline substances, including alloys, intermetallics, and minerals. Under an agreement recently signed with an instrument manufacturer, the NSD has been incorporated into an electron diffraction instrument for automatic phase characterization and identification. The new electron diffraction software searches the NSD by elemental composition, retrieves the full structural crystallographic information, and uses this to generate a calculated or simulated electron diffraction pattern. Unknown phases can then be identified automatically by matching the calculated patterns with the observed patterns generated using the electron backscatter diffraction technique, an increasingly popular scanning electron microscope-based technique used for the analysis of samples in materials science, geology, microelectronics and related research fields.Citation
