This paper presents the results of texture formation in zirconium-based alloy during deformation and heat treatment of tubes. Information about mechanisms and patterns of texture formation in zirconium alloys is necessary for obtaining of products with given anisotropy of physical and mechanical properties. There are considered the basic stages of technological processing of ingot: hot extrusion, cold rolling and intermediate heat treatment. Location of basal normal within a zone, extended along the T – R – T diameter of the stereographic sample projection is common for all pressing textures, determined by the symmetry of the deformation scheme (R, T and L are the radial, tangential and longitudinal direction in the tube, respectively). Peculiarities of distribution of basal normal within the specified zone depend on the nominal process parameters and structural characteristics of the material. Variation in the pressing of temperature and stress state (extrusion and Q-factor), as well as variation of modes of preceding and subsequent heat treatment, provide a wide range of emerging types of crystallographic texture. The structural state of pressed tube billet make a significant influence on its resulting texture. During the hot deformation, the type of formed texture mainly depends on the pressing temperature, i. e. on the ratio of α- and β-phase in the material during its deformation. Considering the cold tube rolling, the Q-factor (stress state in the tube billet) is the decisive, and enhanced basal component of the texture rolling tube (fR/fT ratio) grows with increasing values of Q-factor. The total amount of deformation, achieved at each redistribution, determines the completeness of reorientation of normals at the stage of plastic deformation and their subsequent stability during recrystallization annealing.
