SF analysis on the primary \(\{11\bar{2}2\}\) and secondary \(\{10\bar{1}2\}\) twin systems under the rolling condition, i.e., the compression along the ND. Here, the parent grain is assumed to have a perfect TD split basal texture with a randomly oriented a-axis, i.e., φ1 = 180°, Φ = 30°, and 0° ≤ φ2 ≤60°, and the secondary \(\{10\bar{1}2\}\) twinning is assumed to occur in primary twin variant C2a (φ1 = 124°, Φ = 84°, φ2 = 35°). (0001) pole figure showing the locations of the high SF variants is presented in the right panel; the primary \(\{11\bar{2}2\}\) twin variants with a SF of >~0.38 (black circle) and secondary \(\{10\bar{1}2\}\) twin variants with a SF of >0.4 (red circle).
