Misorientations in rolled and recrystallized zirconium compared with random distribution. A new scheme of misorientation analysis

The noncorrelated misorientation distributions found in a zirconium alloy after deformation, complete recrystallization and subsequent grain growth are first compared with those found in a quasi-isotropic hexagonal material (i.e. associated with a random orientation distribution). They are then recalculated with respect to the specific misorientation axes <0001>, <> and <>. The results are discussed with reference to the specific misorientations that are often assumed to play a role during the recrystallization process.
