Reconstruction

Description: Reconstruction.tif
  1. EBSD HDF5 File - This is the name and location of the .h5ebsd file you wish to reconstruct
  2. Input Parameters - These are all the options that can be set to control the reconstruction
    1. Start Slice and End Slice - This defines the range of sections you wish to reconstruct. The user can choose to only import a subset of the entire dataset, you can choose to not reconstruct everything you imported.
    2. Alignment Method - This allows the user to choose the method used to align neighboring sections. Outer Boundary simply tries to align the area identified as sample on each section. Minimum Disorientation moves the sections until there is a minimum value of disorientation between all voxels in one section and the voxel directly above it in the next section. Mutual information segments each section independently and then performs a mutual information analysis on the grain ids.
    3. Min Grain Size - This a clean-up filter that can be set to merge grains below a defined size after grains have been formed. The voxels of the removed grains are reset to unassigned and then the region is filled in by a local grain growth algorithm.
    4. Disorient. Tol. - This is the orientation difference tolerance allowed between neighboring voxels before they are declared to belong to different grains. Neighboring voxels with misorientations lower than the tolerance are joined during a burn algorithm.
    5. Merge Twins - This is an option that will indentify neighboring grains that have a twin relationship (3,5,9) and merge them together. Effectively, this is a second burn algorithm (performed on the identified grains, rather than the individual voxels) using the specific twin misorientations as a joining criterion rather than the misorientation tolerance used for forming the grains.
    6. Merge Colonies - This is an option that is similar to the Merge Twins option, but will reconstruct prior beta grains in an alpha-beta titanium microstructure. It will first identify grains (which would be alpha colonies in a transformed beta microstructure) and then perform a burn algorithm on neighboring grains/colonies, using the specific misorientations between alpha variants from the same beta grain as the joining criterion.

    8. Phase Types - These are required descriptors to classify the ÔtypeÕ of phase each phase in the EBSD scan. These classifications are used when moving the data to the Synthetic Builder, but are not critical to the reconstruction itself only the statistics calculations.
    9. Quality Metric Filters These are filters that are applied to the input data that determines which voxels are "Good" and which voxels are "Bad". For a voxel to be considered a "Good" voxel every filter must evaluate to true.
