(a) Variation of interfacial energies of O-line interfaces with the OR for two types of Burgers vector pairs: $\left[\overline{1}10\left]\mathrm{f}/2|\right[\overline{1}00\right]\mathrm{b}$ and $\left[01\overline{1}\right]\mathrm{f}/2|\left[\overline{1}1\overline{1}\right]\mathrm{b}/2$. (b) Atomic structure of an $\left[01\overline{1}\left]\mathrm{f}/2|\right[\overline{1}1\overline{1}\right]\mathrm{b}/2$ O-line interface with δ≈−11.1°, showing dissociation of misfit dislocations into stacking faults. The viewing direction is $\left[\overline{1}01\right]\mathrm{f}|\left[\overline{1}\overline{1}1\right]\mathrm{b}$. Green, blue and red points are identified as positions with local fcc, bcc and hcp symmetries, respectively.
