The data is arranged into 3 folders: 1. SEM folder, which contains the raw SEM images of the microstructure of the materials, fracture surfaces, EDS elemental maps and EBSD analysis 2. TEM folder, which contains the raw TEM images of the sintered materials with the corresponding selected area diffraction (SAED) patterns and dark field (DF) images 3. Mechanical tests folder contains the results of tensile tests and nanoindentation. Details of all of the above experiments are presented in the reference article.
