Figure 9. Microstructural features observed prior to mechanical twinning. (A) Network of in-plane dislocations showing extended nodes and corresponding diffraction pattern. (B) Interactions of two families of stacking faults, where the stacking faults of the first family are edge-on (indicated by white arrowheads) and the stacking faults of the second family are close to in-plane (indicated by red arrowheads). The corresponding diffraction pattern shows streaks perpendicular to edge-on stacking faults[32].
