A series of tensile tests for Zr-Sn-Nb alloy strip was carried out at 25℃, 200℃ and 400℃. The effect of texture on the mechanical properties of zirconium alloy was studied by Electron Backscatter Diffraction (EBSD). The results show that Zr-Sn-Nb alloy strip possessed typical basal texture with twin peaks, and [0002] basal poles (in TD-ND plane) tilted ±30° in TD. The larger grains mostly belonged to the {0001} < > and {0001} < > texture while the smaller grains were in the {0001} < > orientation. Due to the texture, the strip presented mechanical anisotropy. The σs was highest in TD and lowest in RD; the σb was highest in RD and lowest in 45° direction. With the increase of temperature, both σs and σb decreased. Besides, Δσs and Δσb decreased too, but Δσs decreased more obviously. The elongation of strip increased with the temperature increasing. However, the elongation of strip at 400℃ was smaller than that at 200℃,which may be induced by the decrease of grain boundary strength and dynamic strain aging phenomenon.
