Fig.7. Atom map of Cr and Ni at the vicinity of G phase (The volume analyzed is 15 nm×15 nm×15 nm) (a), and composition profile of Cr and Ni across G phase, suggesting the low Cr content of G phase (b) (The direction of the composition profile is indicated by the arrow in Fig.7a. The range of G phase in Fig.7b is marked according to the variation of Ni content rather than Cr content due to the Cr fluctuation induced by spinodal decomposition)Color online
