Figure 11
EBSD map around a hillock situated at the junction of three TRDs (reconstructed by ignoring only the Σ3 and Σ9 boundaries). The conventions for the colours of the boundaries are the same as that of Fig. 10[link]. The hillock (at the centre of the figure, in blue) is connected to the left TRD (in brown) by two misorientations that form a triple junction constituted by the rotations R12 = (38.7°, [[4 \bar1 3]]), R23 = (39.3°, [101]) and R13 = (59.1°, [434]). These are close to the Σ81+a, Σ9 and Σ81d operators, respectively. Their composition verifies the groupoid composition Table 3[link]. We conclude that the hillock is a twinned branch of the left TRD and not a new nucleated TRD.
