Extended Data Fig. 1: STEM and APT characterization of the superlattice steel before radiation.

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

Extended Data Fig. 1

a, STEM micrograph. b, High-resolution HAADF-STEM micrograph of the steel specimen taken along the 001 zone axis. The contrast in the HAADF imaging originates from different atomic numbers (Z), and dark columns arise from the partitioning of Al atoms. c, Combined elemental mapping of the APT datasets. d, NPs highlighted by an isoconcentration surface encompassing regions containing more than 50 at% of Al and Ni combined.
