Texture changes in tubes made of Zr-2.5% Nb upon recrystallization

1.	Recrystallization of -zirconium in tubes of Zr-2.5% Nb alloy is associated with reorientation of basal normals; as a result, the rolling texture with a predominant component becomes a texture with a predominant component (0001)±30–50° R-T .
2.	The tendency of grains of -zirconium to recrystallization associated with the rotation of the crystal lattice about the basal normal depends on the orientation of this normal.
3.	We have proposed a model that relates the peculiarities of the development of the recrystallization texture of -zirconium to the structural anisotropy of the rolled material.
