Abstract
Deformation modes have strong effects on deformation textures and subsequent annealing textures during hot working of metals Microtextures and macrotextures during hot axisymmetric and planar compressive deformation and subsequent annealing processes of AlZnMgCuZr alloy were investigated by EBSD and XRD respectively The EBSD testing indicated that for the axisymmetric compressive deformation Brass along the αfiber and Goss present in the sample deformed at 350 °C RotatedCube was present and Brass transformed to Goss along αfiber after annealing RotatedCube appeared only in the deformation at 420 °C which decreased and Brass appeared after annealing For the planar compressive deformation RotatedCube and Brass aligned to α and β fibers present in the deformation at 350 °C RotatedCube texture transformed to Brass along the αfiber after annealing RotatedCube and Brass were present in the deformation at 420 °C and the RotatedCube was enhanced and Brass transformed to Goss after annealing Shearing textures dominated on the surface of the specimen XRD testing showed that RotatedCube and a few Goss dominated in the thickplates formed by upsetting and drawing which transformed to Cube after annealing However Brass and Cube textures present in the thickplates formed by rolling besides RotatedCube and Goss textures which remained in the plates after annealing
