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

Abstract

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〉, 〈10{\overline 1}0〉 and 〈11{\overline 2}0〉. The results are discussed with reference to the specific misorientations that are often assumed to play a role during the recrystallization process.
