a APT reconstruction showing two γ/γ′ interfaces and a SF in the γ′ precipitate. The SF is connected with a PD. b Close-up of the fault region and PD. c Enlarged view from the dashed rectangle in (b), and the 2D projection of Cr highlights that PD is more enriched with Cr compared to the associated SF. d Views along X- and Y-axis showing the distribution of 4 at% Cr iso-compositional surface from γ/γ′ interface to SF and PD. e 1D compositional profile of Co, Cr and Re perpendicular to SF. f 1D compositional profile of Co, Cr and Re perpendicular to PD. Scale bar: a 500 nm. The error bars in (e, f) are estimated as described in Methods section.
