The data is arranged into 4 folders: 1. GIXRD folder, which contains Grazing Incidence X-ray diffraction experiments raw data 2. Nanoindentation folder, where one may find the raw data of load-depth nanoindentation experiments. In the folder data is arranged in 4 subfolders referring separately to each material (A4N-alumina-ODS; Y2N-yttria-ODS, Z3N-zirconia ODS and R2N-non-ODS). In each sub-folder, you can find data sorted by sample condition (virgin or irradiated with different doses). In each of these folders datasets are organized referring to applied maximum load. 3. SEM/EBSD and STEM contains scanning electron microscopy images of materials. 4. TEM contains transmission microscopic images In addition, the file "Density.xlsx" (separated from above-mentioned folders), contains density measurements of the produced materials. Details of all of the above experiments are presented in the reference article.
