Figure 8.

(a) Schematics showing the main concept of the relation between the in-grain misorientation axis and the activated slip system; (b) ND inverse pole figure maps and related in-grain misorientation axis analysis taken for four randomly-selected grains from the AZ31 and AZ31-0.5Ca alloys. The two examples indicated by the dashed circles (grains 1 in the AZ31 and AZ31-0.5Ca alloys) show the shifting of the misorientation axis toward <0001> in the AZ31-0.5Ca and toward $\langle 2\overline{1}\overline{1}0\rangle –\langle 10\overline{1}0\rangle$ in AZ31.
