Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Backscattered electron micrographs provide information about the thickness of the thermally grown oxide (TGO) thickness and the alloy-TGO interface roughness caused by oxidation of FeCrAlY alloy for 100 h at 1025 ºC in dry air upon exposure to corrosive deposits comprising mixed oxides, mixed sulfates, or calcium sulfate. Micrographs were processed to provide tabulated values for TGO thickness as a function of location across the sample cross section, and changes in the TGO-alloy interface position. The purpose of release is to provide access to detailed data related to alloy hot corrosion process. It is released now to correspond with the publication of the analyzed results in a related paper.
