Fig. 3. Dataset of an oxidised Nickel-based alloy (corroded in hydrogenated steam at 480°C) (). (A) Point-cloud and isoconcentration surfaces highlighting the internal oxidation process coming from the surface as well as small oxide islands in the bulk of the sample. (B) Individual cluster isolated from within the data using a cluster-identification method, highlighted with the yellow cube in (A). (C) First nearest-neighbour distribution for Cr showing a slight clustering tendency. (D) Composition profile in the form of a proximity histogram from the isoconcentration surface within the yellow cube in (A).
