“…In addition, in the Zr-Nb system, especially Zr-2.5Nb alloy, the content of Nb exceeds the solution limit of the service temperature, which undermines the corrosion resistance of the alloy. In contrast, the N18 was more competent to the harsh service environment [24][25][26][27][28]. Generally, Zr-1Sn-0.3Nb-0.3Fe-0.1Cr alloy sheets are used as cladding materials, whose service properties are very sensitive to its microstructure.…”

In the present work, the sheets of Zr-1Sn-0.3Nb-0.3Fe-0.1Cr alloy were hot rolled with different reductions (10%, 30%, 50%, and 60%) at 1023 K and 1073 K. The microstructure evolutions including grain microstructure, texture, and dislocation were investigated, using electron backscattering diffraction and transmission electron microscope. The results showed that dislocation slip, twinning, and dynamic recrystallization (DRX) were the main deformation mechanisms. DRX was found to be promoted by larger reduction and higher rolling temperature. The predominant texture formed during hot rolling was basal <0001>//ND, whose intensity reached peak value after 30% reduction hot rolling. While the intensity of DRX texture <10-10>//ND and <1-210>//ND increased with increasing reduction and temperature. This study provided an effective way to tailor the texture and microstructure of the alloy, for optimizing process parameters.
