Fig.9. The orientation maps (a, d) and {0001} pole figures (b, e) of the twinned (a, b) and untwined (d, e) grains after 1-pass forging, and distributions of Schmid factor for {101ˉ2} tensile twinning (c) and basal <a> slip (f) in {0001} pole figure (Due to the inhibition of LPSO phases, twinning propagation is arrested. While twining nucleation is promoted and multiple fine twins constitutes a coarse twin by twins-merging, as indicated by the ellipse in Fig.9a. The twin variants are marked as T1 and T2. The matrices of different grains are marked as A~E)
