Insert Transformation Phases

Group (Subgroup)

Synthetic Building Filters (Packing)

Description

Takes an already formed voxelized structure and inserts transformation phase morphologies with the correct orientation relationship (and habit plane if coherent). Note that cell level data will be updated/changed during the execution of this filter and feature level data will effectively become invalid and should be recomputed. A Prebuilt Pipeline that demonstrates its use is also included in the filter.

Example Output

Using the include example pipeline, the before and after images are presented:

Before (IPF Coloring) After (IPF Coloring)
Synthetically Generated Microstructure Synthetically Generated Microstructure after inserting a transformation phase.

Parameters

Name Type Description
Parent Phase Int The phase which the transformation phase is inserted.
Transformation Phase Thickness Float (Fraction between zero and 1) The fraction of the current grain's sphere equivalent diameter.
Average Number Of Transformation Phases Per Feature Integer This will vary between zero and 2 times the input value
Coherent Fraction Float (Fraction between zero and 1) THe coherent vs. incoherent transformation phase fraction.
"Peninsula" Transformation Phase Fraction Float (Fraction between zero and 1) Specific transformation phases that do not fully section the feature. Variable peninsula lengths will result.
Variant Number Integer (Between 1 and the maximum number of variants)
Transformation Phase Crystal Structure Default numeric values set in EBSDLib Hexagonal = 0, Cubic = 1

Type Default Name Description Comment Filters Known to Create Data
Cell FeatureIds Ids (ints) that specify to which Feature 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 Features (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)
Cell CellEulerAngles Three (3) angles (floats) defining the orientation of each Cell in Bunge convention (Z-X-Z) Import Orientation File(s) to H5Ebsd (IO)
Cell CellPhases The phase of each cell
Feature AvgQuats Five (4) values (floats) defining the average orientation of the Feature in quaternion representation Filter will calculate average quaternions for Features if not already calculated. Find Feature 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 Comment
Feature Active Boolean value specifying if the Feature is still in the sample (1 if the Feature is in the sample and 0 if it is not). At the end of the filter, all Features will be "Active" as the "Inactive" Features will have been removed.
Feature FeatureParentIds List of grouped microtexture region Features.
Feature NumFeaturesPerParent Int of the number of Features contained in each Feature.
