Magnesium alloy AZ61 was processed by several thermomechanical routes consisting of hot-rolling at a high strain rate epsilon = 1.6 s(-1) and intermediate annealing. The total reduction of thickness was 83 % after three routes. Intermediate annealing between routes was necessary to avoid sample fracture and to enhance the ductility. Texture investigations revealed that the basal type texture after deformation changed during a short time of annealing and the {11 (2) over bar0}<10<(1)over bar>0> component was strengthened. The structure investigations after rolling show the occurrence of a large fraction of twins inside the grains while after annealing no twins were left. It was found that the twins formed during rolling may support the texture transformation during annealing and enhance the ductility.
