Crystal Orientation Mapping

In crystal orientation mapping, the electron beam is scanned over the sample on a grid of points and at each point a diffraction pattern obtained and the crystal orientation measured.   The resulting data can be displayed as a crystal orientation map and processed to provide a wide variety of information about the sample microstructure (Figure 2).  Large sample areas can be measured by automatically moving the SEM stage between successive maps.

The maps shown are based on the sample normal, rolling and transverse directions.  At each point in the map, the crystallographic direction corresponding to the particular sample direction is calculated and a colour allocated according to its position in the inverse pole figure (Figure 3).
