Fig. 2. Cr atom maps of binary Fe-20 at.% Cr alloy for: (a) solutionized condition, and aged at 773 K for time durations of: (b) 1 h, (c) 25 h and (d) 50 h respectively. Each purple dot represents one Cr atom. The inset shown in the upper right corners of each image corresponds comparative plots of observed Cr atom distribution with random binomial distribution.
