Figure 3.18 shows a schematic representation of double-oriented-kebab strac-ture. Stacks of parent lamellae is responsible for meridional scattering the SAXS patterns, whereas stacks of daughter lamellae exhibited equatorial scattering. The equatorial scattering is attributed to the overlap of scattering from daughter lamellae and shish. 

After 10 min of sintering (Fig. 50c) many of the kebabs contain several double striations and are more randomly oriented relative to the shish core (which,...
