Reconstruction Filters

Description

In Ti alpha-beta alloys, cooling from the beta (BCC) phase slowly to the alpha phase (HCP) produces collections of alpha phase within a beta grain that are referred to as alpha colonies.
Once the user has segmented the grains, this Filter can be run.
This Filter looks at neighboring grains (as defined by the Segment Grains (Misorientation) Filter) and asks for their misorientation (i.e., the misorientation between the average orientation(s) of the two grains). If the misorientation is found to be "special", i.e., one of the six (6) possible misorientations between colonies transformed from the same beta grain, then the grains are merged together and called one grain. Hence, the outputs of this Filter are the beta grains, because all the colonies transformed from a beta grain will all have the same grain id.
