Abstract Scope |
The study employed a combination of correlative and in situ techniques, specifically transmission electron microscopy (TEM) and atom probe tomography (APT), to investigate the initial stages of oxide film formation in a high entropy alloy (HEA). The research aimed to gain insight into the mechanisms of oxide film formation and the chemical changes that occur during the process. By analyzing the nano-scale chemical changes of the oxide film and the underlying HEA as a function of time, we observed the phase transformation pathway resulting from a single-layer to a multi-layer oxide film, which provided important insights into the process of oxide film formation. The study demonstrates the potential of these techniques in providing a deeper understanding of the processes involved in oxide film formation, enabling the design of materials with improved corrosion resistance and durability. |
