(a) Interfacial energies of interfaces that contain the IL direction with the OR determined by the lowest-energy O-line interface. (b) Equilibrium cross-section morphology determined by a Wulff construction using the energy data in a. c, d are similar to a, b with the O-line OR in a duplex stainless steel. φ represents the angle between the interface and the O-line interface (OLI). e, f represent interfacial structures of $\Delta {\mathbf{g}}_{(\overline{1}11)\mathrm{f}}$ and Δg_(200)f in c, respectively. Atoms are coloured by their structure, e.g., the green atoms locate at the cores of dislocations with a Burgers vector of ${\left[01\overline{1}\right]}_{\mathrm{f}}/2$.
