Detailed Structural and Microstructural Characterization by X-ray Powder Diffraction of AISI 316L Austenitic Stainless Steel under Different Cold-Working Conditions

This dataset contains the complete set of experimental powder X-ray diffraction (PXRD) data and Sindarin text used to perform the microstructural and quantitative phase analyses reported in the manuscript “Detailed Structural and Microstructural Characterization by X-ray Powder Diffraction of AISI 316L Austenitic Stainless Steel under Different Cold-Working Conditions.” The data cover all processing conditions investigated: as-received (R), shot-peened (SP), and cold-rolled samples with 10%, 20%, and 30% thickness reduction (CR10, CR20, CR30).
For each sample, the repository provides:
(i) High-statistics PXRD scans in restricted 2θ windows around the main austenite peaks, used for microstructural analysis via Whole Powder Pattern Modelling (WPPM);
(ii) Wide-range PXRD scans (40–100° 2θ) used for quantitative phase analysis by Rietveld refinement;
(iii) The corresponding Sindarin text files (plain-text) that define the structural and microstructural models, refinement parameters, and optimization commands used in the Nimloth software. Together, these files allow full reproduction of the crystallite size, microstrain, stacking fault, and phase fraction results presented in the manuscript.
Files are organized in folders by sample and calculation type (e.g. R/Microstructure, CR20/QPA), with a consistent naming convention for PXRD data and Sindarin text (e.g. cr10qpa.xy, cr10qpa.sin). The Sindarin text are intended to be executed with the Nimloth application (www.nimloth.app), but they can also serve as human-readable documentation of the WPPM and Rietveld models employed. Users are encouraged to reuse these data and Sindarin text for benchmarking, method comparison, or adaptation of the PXRD–WPPM workflow to other metallic systems, provided appropriate citation of the associated article and this dataset.
