Therefore, the annealed thin films do not exhibit a preferential orientation of crystals, and α-phase grains are randomly distributed
in thin film which can be considered as non-textured. The
absence of texture has been also observed for all thin films regardless
of their thicknesses, which might be due to the ultra-fine structure of
thin films. In addition, annealing does notmodify the texture of the initial
α-phase, but it may influence the texture of the newly developed γ-
phase that grows during annealing.
