Spatially propagating martensitic transformation enables strength–ductility synergy in gradient-structured L-PBF 316L stainless steel

Description

This database contains three experimental data files: stress-strain.csv, XRD.csv, and LUR.csv. The stress-strain.csv file records the stress–strain responses obtained from uniaxial tensile tests and is used to evaluate the mechanical properties of the material, including elastic behavior, tensile strength, ductility, and fracture characteristics. The XRD.csv file contains X-ray diffraction (XRD) data used to characterize the crystal structure, phase composition, and crystallinity of the material, where diffraction peak positions and intensities can be used to analyze structural variations. The LUR.csv file contains the response data collected during the LUR experiments, which are intended to investigate the material’s behavior and functional response under specific experimental conditions. All datasets were collected under controlled and standardized experimental procedures, and the data were further organized with unified formatting and units. This database is intended to support the investigation of relationships between microstructural characteristics, experimental responses, and macroscopic mechanical properties, providing foundational data for further analysis, reproducibility studies, structure–property correlation research, and machine learning applications.
