Extended Data Fig. 5: APT characterization of the superlattice steel subjected to 840 dpa at 500 °C.
a, NP labeled by the red arrow in Fig. 2b, which is highlighted by the isoconcentration surface encompassing regions containing more than a 50 at.% combination of Al and Ni. b, Proximity histogram showing the composition change across the selected NPs, especially the Mo profile. c, The solute-enriched region labeled by the blue arrow in Fig. 2b, which is highlighted by the isoconcentration surface encompassing regions containing more than a 50 at.% combination of Al and Ni; Additionally, more than 23 at.% Al and 28 at.% Ni show an inhomogeneous distribution of Ni and Al in the solute-enriched regions. d, Proximity histogram showing the composition change across the selected solute-enriched regions, revealing the rejection of Mo atoms out of the precipitates and reformation of NPs inside the solute-enriched regions. The error bars represent the standard deviation of the mean.
