The X-ray quantitative texture analysis was used to measure and analyze the cold-rolled texture and the isothermal annealed texture at 40 ℃ for 90% cold-rolled high-purity aluminum sheets. The results show that the main cold-rolled texture components {1 1 4} <2 2 1> During the transition to the recrystallized cubic textured component {0 0 1} <1 0 0>, an intermediate transition textured component - {0 0 1} <1 1 0 > Inverse Gaussian texture component • The main cold-rolled texture component {1 1 4} <2 2 1> and the anti-Gaussian texture component {0 0 1} <1 1 0> There are respectively 1 95 ° <1 1 0> and 1 8 4 ° <1 0 0> between the compositional component {0 1 3} <0 31> and the cubic textured component {0 0 1} <1 0 0> The relationship between the orientation of high-purity aluminum recrystallization texture evolution can be described as {1 1 2} <1 1 1> + {0 1 3} <0 31> → {0 0 1} <1 1 0> → {0 0 1} <1 1 0> + {0 0 1} <1 0 0> → {0 0 1} <1 0 0>
