Fig. 10.. EBSD band contrast maps of (a-c) AZ64 and (d-f) AZT643 samples superimposed by specific twin boundaries at different stages of tensile strain: 10$\bar{1}$2 extension twins identified by red lines reorient the basal planes by 86°, 10$\bar{1}$1 contraction twins marked by blue lines reorient the basal planes by 56° and 10$\bar{1}$1-10$\bar{1}$2 double twins in green lines reorient the basal planes by 38°.
