Representation of grains and grain boundaries

Unlike in an optical or scanning electron micrograph, the crystal orientation map must reveal the positions of all grains and grain boundaries in the sample microstructure (Figure 5).  In crystal orientation mapping a grain is defined by the collection of neighbouring pixels in the map which have a misorientation less than a certain threshold angle.  The distribution of grain sizes can be measured from the data collected for the map.  In addition, the distribution of grain boundary misorientation angles and the distribution and position of special grain boundaries can be shown.
