Phase discrimination using Electron Backscatter Diffraction (EBSD) is a powerful tool for the positive identification of phases that exist in materials at the microscopic level. Accurate phase identification is a basic requirement of an EBSD system. This technical note illustrates the capability of Oxford Instruments’ AZtecSynergy microanalysis system using the Tru-I® indexing engine to perform Phase Identification. This is coupled with simultaneous EBSD and X-ray chemical mapping. A high-temperature steel containing second phase particles is used as an example material, this sample contains phases which are traditionally very difficult to differentiate using EBSD.
