In our work, the textures of three zirconium-alloys tubes were compared with the textures of seven alpha zirconium samples deformed by uniaxial tension from strain 5% to strain 30% (strain step 5%). The texture measurements by neutron diffraction were performed on the KSN-2 neutron diffractometer located at the research reactor LVR-15 of the Research Centre Řež, Czech Republic. 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. It was found that the (100) and (110) plane poles are oriented parallel towards the rolling direction for both types of samples. All samples have preferred orientation of planes (102) and (103) perpendicular to normal direction. More significant tilt of basal poles from the normal direction toward the transverse direction which indicates twinning was observed for alpha zirconium. Consequently, alloying of zirconium create ideal texture with respect to zirconium hydride creation. The alloying of zirconium is reflected in decreasing the overall texture sharpness. The obtained results are characteristic for zirconium.

“…Value p hkil > 1 along a certain specimen direction says that, within the tested sample volume, more crystalline grains are oriented by the examined plane {hkil poles parallel to the selected specimen direction than it is the case in the untextured specimen. The method and its application on characterization of zirconium textures is in more details described elsewhere (Vetvicka, 2014). Figure 2 shows the positions of crystallographic poles within the inverse pole figure of zirconium.…”

Two series of zirconium samples were investigated by neutron and X-ray diffraction. First series of the samples was deformed at room temperature (RT), whereas the second series was deformed at 300 °C. Both series were deformed on uniaxial tensile machine INSTRON 5882 from strain 0 to 30% (strain step was 5%). The neutronographic texture measurements were performed on the KSN-2 neutron diffractometer located at the research reactor LVR-15 in the Nuclear Research Institute, plc. Rez, Czech Republic. The X-ray measurements were performed at the theta/theta X'Pert PRO diffractometer with the Cr X-ray tube. Observed data were processed by the software packages GSAS and X'Pert Texture. Preferential orientation of the $\left({10\bar 10} \right)$ and $\left({11\bar 20} \right)$ plane poles is found to be parallel to the rolling direction for both tested deformation series. Poles of the $\lpar 10\bar 12\rpar $ and $\lpar 10\bar 13\rpar $ planes tend to be parallel to the normal direction (Tables II and III). Orientation of the basal poles is tilted by 45° from the normal direction toward the transverse direction. Sharpness of the resulting texture increases with extends of the applied deformation as well as with rise of the tensile test temperature from the RT level to 300 °C.

“…Under these conditions fuel claddings degrading their properties and creep cause tube deformation and texture changes in the alloy. So it is necessary that the fuel claddings to preserve their mechanical, structural, and chemical properties during various types of accidental conditions [5][6][7][8][9][10].…”
