Measuring Grain Size using EBSD

Electron backscatter diffraction (EBSD) is an ideal technique for measuring the grain size of materials on the micrometre to millimetre scale. Recent advances in detector technology, such as the fibre-optically coupled Symmetry S2 detector, deliver exceptionally high speed data collection that enables grain size measurements in just a few seconds. In this video we demonstrate how EBSD can be used to measure the grain size in a twinned austenitic steel sample, explaining some of the key parameters and showing the measurement tools available in both our AZtec acquisition platform and our new EBSD data processing software, AZtecCrystal.

Thanks for the video. I would like to ask you how to measure the GND (geometrically necessary dislocation) by using this software. Thanks

is the software can measure the particale sizes birgger then mm , i mean for grain as 10 cm from High quality image ?
