Visualizing the Nanoscale Oxygen and Cation Transport Mechanisms during the Early Stages of Oxidation of Fe–Cr–Ni Alloy Using In Situ Atom Probe Tomography (Adv. Mater. Interfaces 20/2022)

In Situ Atom Probe Tomography Using Isotopic Tracer article number 2200134, Arun Devaraj and co-workers report that in situ atom probe tomography using 18O isotopic tracer is correlated with ex multimodal characterization computational simulations. This approach validates the outward cation diffusion mechanism as dominant during early stages of oxidation Fe–18Cr–14Ni alloy. a rapid to study high-temperature oxygen–material interactions, relevant studies material degradation catalysis.
