Nano/ultra-fine grained W and W-1wt%La2O3 (80nm–320nm) were fabricated by high-pressure torsion after 2 turns at 300°C/200°C, 400°C, 550°C and 700°C. Distinct textures were observed by using electron backscattering diffraction. Deformed W primarily revealed {112}〈111〉, {110}〈112〉 and {110}〈001〉 components, whereas, deformed W-1wt%La2O3 exhibited mainly γ-fiber at lower process temperatures. The texture anisotropy of (112)[1−1−1] and (112)[111−] pair was also investigated. Results showed that the stacking fault energy and process temperature were crucial in determining texture. Dynamic recrystallization was retarded by La2O3 addition under given conditions.
