It is possible to show on EBSD map projections of vectors normal to the common plane twin 102. Moreover, for a number of selected grains pole figures were prepared: on your own system, TSL and HKL. We can see that:
1. The limits of Twin are very well defined and the directions normal to the planes are generally perpendicular to the grain boundaries
2. Directions are displayed correctly because it agrees with the figures pole 102
3. My program corresponds to the convention TSL (x-down, y-right), working with HKLem requires caution
Keep in mind that if we want to apply the criterion described geometry of the border, there is no way to manipulate orientations gathered by EDAX system by changing the sample:

To determine the boundaries of applied algorithm, which recognize the grain due to the consistency of orientation. Then, as highlighted objects have been extended through translation unit in two independent directions. Created incidence matrix grains, and the boundaries were determined by multiplying the expanded neighboring grains. On the map the boundaries of tolerance dezorientacjach 10 ° angle for ideal angle of 60 ° and 10 ° axis tolerance for the ideal axis 111.
