11.11. Compute Feature Reference Misorientations
Group (Subgroup)
Statistics (Crystallography)
Description
This Filter calculates the misorientation angle between each Cell within a Feature and a reference orientation for that Feature. The user can choose the reference orientation to be used for the Features from a drop-down menu. The options for the reference orientation are the average orientation of the Feature or the orientation of the Cell that is furthest from the boundary of the Feature.
Note: the average orientation of the Feature is a typical choice, but if the Feature has undergone plastic deformation and the amount of lattice rotation developed is of interest, then it may be more reasonable to use the orientation near the center of the Feature as it may not have rotated and thus serve as a better reference orientation.
IPF Colors <001> Direction
This is the data set’s IPF colors by the <001> direction which shows the reader the relative orientation gradients within each feature (grain).
Example Using Feature’s Average Orientation
Using the T12-MAI-2010/fw-ar-IF1-aptr12-corr.ctf data set we can generate the following
data using the Feature Average Orientation choice.
Example Using Feature’s Euclidean Center Voxel’s Orientation
Using the same dataset, the algorithm will find the voxel that is the furthest from the feature boundary, and use that voxel’s orientation as the reference orientation.
