Supplementary experimental data for SPS sintering of martensitic stainless steel

The dataset contains selected supplementary experimental data supporting research on Spark Plasma Sintering (SPS) of martensitic stainless steel. It includes illustrative figures published in the associated article, such as SEM and EDS images of powders, XRD patterns, schematic diagrams of the SPS process, microstructures after selected processing steps, and representative process curves. The data are provided for documentation and transparency purposes and do not constitute a complete set of raw experimental data.
