What is Electron Backscatter Diffraction (EBSD)?

WebTheory. The orientation distribution function (ODF) is a function on the orientation space that associates to each orientation g the volume percentage of crystals in a polycrystaline specimen that are in this specific orientation, i.e., o d f ( g) = 1 V d V ( g) d g. In MTEX an entirely random texure will have an ODF constant to one.
