Fig. 2: Absence of apparent segregation of Bi atoms in {10\(\overline 1\)2} CTB.
From: Unusual solute segregation phenomenon in coherent twin boundaries
HAADF-STEM images showing {10\(\overline 1\)2} CTBs in Mg–0.4Bi alloy: a aged at 160 °C for 1 h, b 160 °C for 300 h, c 80 °C for 48 h, and d 80 °C for 200 h. Enlarged images of TBs are shown as insets in the upper-right, revealing that no Bi-rich columns are detected at {10\(\overline 1\)2} CTBs. The alternating compression and extension sites of the CTB are marked by orange and yellow dash-line circles, respectively.
