Abstract
Deformation modes have strong effects on deformation textures and subsequent annealing textures during hot working of metals. Micro-textures and macro-textures during hot axisymmetric and planar compressive deformation and subsequent annealing processes of Al-Zn-Mg-Cu-Zr alloy were investigated by EBSD and XRD respectively. The EBSD testing indicated that for the axisymmetric compressive deformation, Brass along the α-fiber and Goss present in the sample deformed at 350 °C, Rotated-Cube was present and Brass transformed to Goss along α-fiber after annealing; Rotated-Cube appeared only in the deformation at 420 °C, which decreased and Brass appeared after annealing. For the planar compressive deformation, Rotated-Cube and Brass aligned to α and β fibers present in the deformation at 350 °C, Rotated-Cube texture transformed to Brass along the α-fiber after annealing; Rotated-Cube and Brass were present in the deformation at 420 °C, and the Rotated-Cube was enhanced and Brass transformed to Goss after annealing. Shearing textures dominated on the surface of the specimen. XRD testing showed that Rotated-Cube and a few Goss dominated in the thick-plates formed by upsetting and drawing, which transformed to Cube after annealing; However, Brass and Cube textures present in the thick-plates formed by rolling besides Rotated-Cube and Goss textures, which remained in the plates after annealing.
