图8 LPSO/SFs内扭折界面(KB)与{ $10 \bar{1} 2$ }孪晶共存形貌

Fig.8 Low-magnification HAADF-STEM images of a region containing twin and kink boundary (KB) between the high-density SFs or LPSO structure
(a) the matrix with KB was surrounded by the twins
(b) KB connected with TB, which was also connected with a triangle matrix (denoted by red arrows)
(c) zoom-in image of the area “M” shows the triangle matrix 3 relates to a BB boundary
(d) atomic-resolution HAADF-STEM image of the area d in Fig.8c indicating that the triple intersection consists of BP, KB, and PB
(e) magnification image of area e in Fig.8b suggesting the formation of dislocations with c Burgers vectors in the LPSO structure (red ⊥) due to the twin shear
