From: A nanoscale co-precipitation approach for property enhancement of Fe-base alloys
Concentration distributions and atoms maps with 11 at.% Cu and 9 at.% Ni isoconcentration surfaces of 2 precipitates reconstructed from the APT data showing the profiles of elements distribution for (a) low nickel alloy and (b) high nickel alloy after aging at 500°C for 10 h in vacuum.
Atom maps show that Ni mainly segregates into the precipitate core in the low nickel alloy, whereas, Ni distributes uniformly around the small Cu-enriched cores and non-uniformly for larger cores in the high nickel alloy.
