Calculation of misorientation distribution between recrystallized grains and deformed matrix

Misorientation between neighboring grains has significant influence on migration of grain boundaries during annealing of cold worked polycrystalline materials. The migration of grain boundaries could lead to formation of unique textures and improvement of materials properties. Theoretical characterization of the misorientation distribution between the deformed matrix and the recrystallized grains can be calculated using the fundamental concepts of the orientation distribution function and Euler's space. There is a maximum in misorientation distribution at approximately 45° to approximately 50°. About 80% of volume fraction is located within the range between 35° to approximately 60°, indicating the prevailing migration of high angle boundaries during recrystallization.
