Fig.5 Grain size diagrams of constant-temperature deformation process at ε = 0.2 (a), ε = 0.4 (b), and ε = 0.6 (c); and step-cooling deformation process at ε = 0.6 (d) (The colored small grains are dynamically recrystallized grains, the red grains are basal orientation, and the other colored grains are non-basal orientation)
