Fig.8. Orientation maps of multi-directional forged alloy after 1-pass (a), 2-pass (b), 3-pass (c) and 6-pass (d) (Twins with smaller size can be observed in the grains with c-axes near parallel to the forging direction, as marked as ellipses in Fig.8a; with the changing of forging direction, untwined grains in the 1-pass are rotated to the favorable orientation for twinning (<
