Identify MicroTexture (C-Axis Misorientation)

Group (Subgroup)

Reconstruction Filters (Grouping)

Description

This Filter groups neighboring Fields that have c-axes aligned within a user defined tolerance. The algorithm for grouping the Fields is analogous to the algorithm for segmenting the Fields - only the average orientation of the Fields are used instead of the orientations of the individual Cells and the criterion for grouping only considers the alignment of the c-axes. The user can specify a tolerance for how closely aligned the c-axes must be for neighbor Fields to be grouped.

NOTE: This filter is intended for use with Heaxgonal materials. While the c-axis is actually just referring to the <001> direction and thus will operate on any symmetry, the utility of grouping by <001> alignment is likely only important/useful in materials with anisotropy in that direction (like materials with Hexagonal symmetry).

Type Default Name Description Comment Filters Known to Create Data
Cell GrainIds Ids (ints) that specify to which Field each Cell belongs. Values should be present from segmentation of experimental data or synthetic generation and cannot be determined by this filter. Not having these values will result in the filter to fail/not execute. Segment Fields (Misorientation, C-Axis Misorientation, Scalar) (Reconstruction), Read Dx File (IO), Read Ph File (IO), Pack Primary Phases (SyntheticBuilding), Insert Precipitate Phases (SyntheticBuilding), Establish Matrix Phase (SyntheticBuilding)

Field AvgQuats Five (5) values (floats) defining the average orientation of the Field in quaternion representation Filter will calculate average quaternions for Fields if not already calculated. Find Field Average Orientations (Statistics)
Ensemble CrystalStructures Enumeration (int) specifying the crystal structure of each Ensemble/phase (Hexagonal=0, Cubic=1, Orthorhombic=2) Values should be present from experimental data or synthetic generation and cannot be determined by this filter. Not having these values will result in the filter to fail/not execute. Read H5Ebsd File (IO), Read Ensemble Info File (IO), Initialize Synthetic Volume (SyntheticBuilding)

Type Default Name Description Comment
Field Active Boolean value specifying if the Field is still in the sample (1 if the Field is in the sample and 0 if it is not) At the end of the filter, all Fields will be "Active" as the "Inactive" Fields will have been removed.
