%X High precision dimensionality tubes are required for a number of applications. Nevertheless, there are some troubles and challenges to produce high quality tubes in a cost-effective way. In recent works done at the Institute of Metallurgy at Clausthal University of Technology, the tube drawing process was optimized by introducing dynamic tilting and shifting of the die. These methods made it possible to control the wall-thickness variation and even residual stresses (RSs) evolution. A possible influence on texture evolution, however, has not yet been investigated, though it is well known that the crystallographic texture has a remarkable effect on materials' properties. Furthermore, the initial texture clearly influences the microstructural evolution during plastic deformation, affecting the RSs evolution and dimension accuracy, too. In this paper the evolution and heterogeneity of the texture are introduced for tube drawing performed with a tilted die. The measurements were done using synchrotron and neutron diffraction methods. The aim was to understand the behavior of the material during the asymmetrical tube drawing, caused by the tilted die, and connect the effects between eccentricity and residual stresses. Pole figures and ODF densities were studied and the creation and variation of different texture components were analyzed as well.
