Fig. 7: Dendritic patterns in DECLIC-DSI.

In situ directional solidification of a SCN-0.46 wt% DC alloy (V = 1.5 μms−1; G = 12 Kcm−1) under microgravity (DECLIC-DSI). Raw images (a) are analyzed to determine each dendrite center and to build Voronoi skeletons (b) that are used to calculate local spacings (scale in µm) and draw maps of primary spacing (c)89.
