【 摘 要 】

Seven zirconium samples were studied by neutron and X-ray diffraction after deformation on uniaxial tensile machine INSTRON 5882 from strain 5% to strain 30% (strain step was 5%). Preferred orientation parameters were determined by using pole figures and inverse pole figures. The X-ray measurements were performed at theta/theta X'Pert PRO diffractometer with Cr X-ray tube. Observed data were processed by software packages GSAS and X'Pert Texture. Our results can be summarized as follows: (i) Samples prefer orientation of planes (100) and (110) perpendicular to rolling direction. (ii) The position of the basal poles is tilted by 30° from the normal direction toward the transverse direction. (III) Samples prefer orientation of planes (102) and (103) perpendicular to normal direction. (iv) Level of resulting texture increases with deformation. The obtained results are characteristic for zirconium.
