Figure 12. HAADF-STEM images of CoCrNi alloy tested to 53% true strain at RT. (A) HAADF-STEM image of a well-developed parallel nanotwin-HCP lath structure. (B) A higher magnification HAADF-STEM image showing the highlighted region in (A)[28]. HAADF-STEM: High-angle annular dark-field scanning transmission electron microscopy; HCP: hexagonal-closed-packed.
