Extended Data Fig. 6: Radiation-induced dissolution and thermally activated reprecipitation of NPs in the superlattice steel.

From: Superior radiation tolerance via reversible disordering–ordering transition of coherent superlattices

Extended Data Fig. 6

a, The number density of NPs versus radiation damage at room temperature (RT). b, Cross-sectional STEM image of the specimen subjected to 5 dpa at room temperature. The inset is the corresponding SAED pattern. c, Cross-sectional STEM image of the specimen irradiated to 5 dpa at room temperature followed by aging at 500 °C for 3 h. d, APT characterization of the superlattice steel irradiated to 5 dpa at room temperature. e, Proximity histogram showing the composition profiles across the selected nanopreccipitates shown in 40 at.% Ni+Al isosurface image (labeled by the red rectangular box). f, Proximity histogram showing the composition profiles across the selected nanoprecipitate shown in 40 at.% Ni+Al isosurface image (labeled by the blue rectangular box). The error bars are the standard deviation of the mean.
