In this work, a hot-rolled and annealed Zr alloy plate with a composition of Zr-1.06Sn-0.36Nb-0.3Fe-0.1Cr-0.13O (wt. %) was compressed along normal direction (0° sample) and transverse direction (90° sample) at 700 ℃ at a strain rate of 1/s. The microstructures and microtextures were characterized by electron backscattered diffraction (EBSD) technique. Visco-plastic self-consistent (VPSC) model was applied to evaluate the activity of slip and twinning systems during deformation at low strain. Microstructure characterization revealed that dynamic recrystallization (DRX) occurs in the two samples. It is found that the texture of the recrystallized grains is similar to that of parent grains, and the preferred nucleation or growth is not in charge of the texture formation. In the 0° sample, all three slip modes (basal, prismatic and pyramidal slip) operate from the first stage of deformation, while a few amount of pyramidal slip is active in the 90° sample in the early stage of deformation. The high activity of prismatic slip results in an intensive <10-10>//RD texture component in the 90° sample. Moreover, predominant basal slip activity at 700 ℃ is necessary to simulate the observed deformed texture.
