Figure 3

Quantification of particle rotations and effect of particle coordination. (a) Top: Plot of the average rotation of particles in the two RoIs illustrated in Fig. 2 and globally for the whole sample, as a function of relative density. The rotations are cumulative over the incremental sintering steps. Below: Cumulative rotations of individual particles in RoI1 (left, 9 particles) and RoI2 (right, 12 particles). The rotation profiles for particles in RoI1 are numbered corresponding to the particle numbers in Fig. 2(b). Particles in RoI1 that lie on the surface of the sample are shown with dashed lines. (b) Showing the mean particle rotations relative to the original arrangement as a function of the number of contacting neighbours, for the whole sample studied.
