Fig. 7: Alteration of dislocation-slip behaviors by short-range ordering.

Chemical short-range ordering is observed in both samples with the L12 type dominantly found in Sample HT. a Two-beam bright-field images of Sample WQ shows long and curved dislocations. Multi-poles (MPs) are also observed here. b Dislocations in Sample HT form extensive slip bands (SBs), where paired dislocations (PDs) are commonly seen in the SBs. The scale bars are 500 nm in length.
