Diffraction with high-energy synchrotron radiation is a new experimental method to determine textures of
materials, which due to the special properties of this radiation, in the future may have advantages in terms
of accuracy of local texture measurements in comparison to established methods like Electron back scatter
diffraction (EBSD). In the present study NiAl polycrystals with two different initial textures have been
deformed in torsion at 727°C and 1000°C and their texture development has been measured with highenergy
synchrotron radiation. Torsion enables the study of texture formation with strain as well as the
exploration of large strains without changing the shape of the samples. The pole figures indicate the preferred
alignment of ‹100› with the shear direction and {110} with the shear plane. High pressure torsion may also
open new possibilities in terms of grain refinement and texture formation and thus ductilization of NiAl.
