The two types of branches observed in dendrites viewed parallel to the [010] direction (location marked in Fig. 3). (a) SE image of part of the curved dendrite shown in Figs 3c and4a. A mean filter of 1 pixel radius was applied to enhance visibility of the branches. The projection of the {001}^* directions (dashed red lines) and < 10–1 > directions (solid blue lines) in the sample plane (obtained from EBSD crystal orientation mapping) is indicated for two profiles along separate branches. The inferred growth directions (G.D.) of the two branches are also indicated. (b) and (c) Equal angle, upper hemisphere pole figure plots of Cpx <010>, {001}^*, and < 10–1 > directions for the profiles in (a). Each pole figure shows the profile for a separate branch. The first and last points of each profile are indicated by a triangle and a square respectively in all plots. The resulting sense of rotation is noted on the pole figures. The lattice curvature calculated from each profile is given above each pole figure.
