Texture evolution behavior and anisotropy of 2A97 Al-Li alloy during recrystallization at elevated temperature

2A97 Al-Li alloy was cold-rolled to 2 mm and then thermally exposed at different temperatures for 1 h and at 723 K for different time, respectively. The texture evolution behavior and the anisotropy of 2A97 Al-Li alloy were investigated. The result shows that the {001} & LANGBRAC;120 & rang; and {011} & LANGBRAC;233 & rang; textures are the dominant recrystallization texture. The {124} & LANGBRAC;211 & rang; texture is the final recrystallization texture. In case of low-temperature thermal exposure (473, 573 K), the {011} & LANGBRAC;211 & rang; texture is aggregated to the {112} & LANGBRAC;111 & rang; and {123} & LANGBRAC;634 & rang; textures. During the recrystallization at 723 K, the {001} & LANGBRAC;110 & rang;, {111} & LANGBRAC;112 & rang; and {011} & LANGBRAC;100 & rang; textures are the intermediate transition grain orientations. The concurrent precipitation of Al20Cu2Mn3 and Al3Zr results in the occurrence of unusually sharp {011} & LANGBRAC;233 & rang; and {001} & LANGBRAC;120 & rang; texture components during recrystallization. The alloy with both recrystallization and deformation texture possesses the smallest anisotropic, and the texture is the direct reason that results in the anisotropy.
