Electron Backscatter Diffraction. The data beneath “coloured maps”

Lecture by John Wheeler, University of Liverpool

EBSD is generally perceived as “coloured” representation of the microstructure of metals and materials in term of grain orientations. Such coloured maps cab be seen simply as qualitative images but in fact contain much quantitative information. 
Indeed EBSD now routinely provides huge datasets of high quality and precision, and this highlights the need to understand how to analyse these quantitatively. This lecture will explain relevant methods and demystify the numerous acronyms we encounter.
Starting from the foundation of this technique, examples and theory will be presented that suggest the application of EBSD to crystalline materials, not only metals.
