Texture evolution in AZ91 alloy after hot rolling and annealing

A commercial AZ91 magnesium alloy with a random initial texture was subjected to homogenization heat treatment (solution annealing) at 450 °C. This resulted in the appearance of a weak triple (0001)-(10 1¯0)-(11 2¯0) fibber texture. After hot rolling at 400 °C, the deformation texture was typically (0001) basal with splitting of the basal poles in the rolling direction. After annealing at 450 °C for 36 h, the annealing texture was the retained deformation texture with more homogeneous distribution of poles around the ideal basal orientation. There was no trace of abnormal grain growth.
