Three alloys with 3.0 at.% Mn (a, b), 4.0 at.% Mn (c, d), and 8.6 at.% Mn (e, f) were studied. The 2D GB in-plane concentration maps are extracted from the 3D APT data, to be comared with simulation results in Fig. 4. The Fe3Mn and Fe4Mn alloys were annealed for 2 months at 450 °C. The Fe9Mn was annealed for 6 h at the same temperature.
