Fig4 Interaction volume measurement -

Measurement and simulation data of EBSD inteaction volume

Includes calculated model & EBSD patterns for measurement
EBSD patterns are from Zircaloy-4 and scanned on a Bruker eFlashHR camera in high resolution mode (1600 x 1200) attached to a Zeiss Auriga-40 SEM. The sample was tilted to 70 degrees and the SEM image shows the tilt corrected scanned region.

Fig14 Error approaching gb -
15 patterns are included that were used to create many simulated grain boundary pairs. These were captured from the same sample as used in Fig4.
The spreadsheet details results shown in Fig 4.

Fig 16 GrainBoundary Pobability -
This describes results from the simple Voronoi tessalation model (virtual grain structure) and sampling with a fixed step size, similar to a real EBSD scan. Probabilities were calcualted for different interaction volume sizes and critical distances.
