From: Triple and double twin interfaces in magnesium—the role of disconnections and facets
(a) Bright field image of the lower portion of the first area of interest, at low magnification; the matrix (M) is depicted in yellow, the secondary twin (\({\textrm{T}}_2\)) in blue, the tertiary twin (\({\textrm{T}}_3\)) in green. (b) HRTEM image of the region denoted by the red circle in (a); boundaries have been drawn using the following colour scheme. Blue: \((10\bar{1}2)\) plane of the matrix and primary twin; yellow: \((10\bar{1}1)\) plane of the primary and secondary twins; red: PB facets of the primary twin, BPy facets of the secondary twin and PPy facets of the double twin; green: BP facets of the primary twin, P3Py facets of the secondary twin and B3Py facets of the double twin; purple: PyB facets of the secondary twin. (c) Indexed SAD pattern of the region denoted by the red circle in (a). (d) HRTEM image of the upper region of (b), higher magnification, colour coding as in (b).
