(a) and (b) are dynamic microstructure developments of TBs with increasing strain ( indicates the applied stress). The black arrowhead in (b) indicates the dislocation half-loops emitted from a TB.

[(a)–(d)] A series of in situ TEM micrographs showing dislocation emissions from a TB with increasing strain. The white arrow in (a) indicates the crack propagation direction. , , TB1, and TB2 represent the matrix lamella, the twin lamella, and twin interfaces, respectively. is the applied stress. One black spot on the specimen is served as a position marker pointed by a black arrowhead in each micrograph.

(a) A high magnification postmortem TEM image of the curved TB2 shown in Fig. 2(d); the inset is a double Thompson’s tetrahedron; the white arrowhead indicates a TB step. (b) A high-resolution TEM image of the TB step arrowed in (a).
