Fig.6. Atom maps of Ni, Si, Mn, P and Cu in δ-ferrite in the unaged (a), 7000 h aged (b) and annealed (c) specimens (The isosurface of 12%Ni, 5%Si, 3.5%Mn, 0.65%P and 0.6%Cu is superimposed on the atom map in Fig.6b in order to characterize the precipitates following 7000 h ageing. The volume analyzed is 80 nm×80 nm×123 nm, 88 nm×88 nm×160 nm and 71 nm×74 nm×89 nm, respectively)
