a Edge on twin-associated χ-lath shown in Fig. 3, b COS analysis and Burgers vector analysis of the ledge step, c magnified inset to determine projected Burgers vector, d possible full Burgers vectors, and e schematic of proposed formation/thickening mechanism. The heat map color scheme indicates deviation from the perfect lattice, where blue is perfect and red shows strong displacement; this highlights regions of HCP-like stacking (planar defects) as well as reveals locations of partial dislocations as to be easily observed.
