a Two planar slip bands and some scatteredly distributed dislocations in between the bands were observed from the zone axis of [2–1–10]. b–e Weak beam dark field (WBDF) images of the same area. b Both planar slip bands and dislocations in between the bands disappeared when g = 0002, which excluded the existence of <c + a> dislocations. c WBDF image using g = 01–10, highlighted the dislocation loops nucleated from the slip bands, as well as the frequent occurrence of possible dislocation cross-slips in between the bands. Some typical examples (areas I and II) were indicated by blue arrows in d and e. A schematic of the crystallographic orientation for the imaging direction is given in f.
