be considered in the determination of suitable warm rolling schedule for acquiring high-quality magnesium sheet and high rate of finished products. However, the extruded sheets having uniform and fine... prismatic regions divided by shear strips due to pile-up of twin crystals; the prismatic regions increase at elevated rolling temperature or at high rolling speed, and finally all are composed of equiaxed......
