Investigation of recrystallization texture evolution during annealing of hot deformed AA3104 alloy
Specimens, taken from hot rolled AA3104 slab, were deformed under plane strain compression conditions. The resulting crystallographic textures, obtained from standard X-ray and EBSD texture measurements, are strongly dependent on the deformation temperatures and strain rates. Two extreme conditions were considered, high Z (low temperature and high strain rate) and low Z (high temperature and low strain rate), which influence the cube texture development during both deformation and annealing. In addition, 3D X-ray Diffraction Microscopy (3DXRD) was utilised to characterise the growth of individual grains within the bulk of the samples deformed at high Z. Nucleation times and growth kinetics were measured in-situ and distributions of these from a population of grains were analysed according to their resulting orientations.
