In this section we explain how to extract specific grain boundaries. Therefore we start by importing some EBSD data and reconstructing the grain structure.
The output of
tells us the number of boundary segments between the different phsaes. Those segments with notIndexed phase include also those boundary segments where the grains are cutted by the scanning boundary. To restrict the grain boundaries to a specific phase transistion you shall do
Similarly we may select all Forsterite to enstatite boundary segements.
Note, that the order of the phase names matter when considering the corresponding misorintations
In the fist case the misorientation returned is from Forsterite to Enstatite and in the second case its exactly the inverse
The selection of grain boundaries according to specific misorientationsm according to twist / tild character or twinning is explained in linked sections.
