This script demonstrates the grain graph approach to parent phase reconstrution in a martensitic material. The methods are described in more detail in the publications Parent grain reconstruction from partially or fully transformed microstructures in MTEX, J. Appl. Cryst. 55, 2022.Crystallography, Morphology, and Martensite Transformation of Prior Austenite in Intercritically Annealed High-Aluminum SteelWe shall use the following sample data set.
