Dataset for "Microstructural and Mechanical Characterization of DURACON 45M Processed by LW‑DED"

This dataset contains all experimental data supporting the publication “Microstructure, Phase Evolution and Mechanical Anisotropy of High-Conductivity DURACON 45M Alloy Fabricated by Laser-Wire Directed Energy Deposition in As-Built Condition”.The data were generated during a comprehensive characterization of DURACON 45M fabricated using laser‑wire directed energy deposition (LW‑DED) and include microstructural, thermal, mechanical and tribological measurements. The dataset provides raw and processed results from: Tensile testing (X, Y, Z orientations) – engineering stress–strain curves, extracted mechanical properties (UTS, Rp0.2, elongation), and DIC strain‑field data. Thermal transport measurements – thermal diffusivity (LFA), heat capacity, density data, and calculated thermal conductivity for all build orientations. Wear testing (pin‑on‑disc) – raw profilometry tracks, wear‑track profiles, wear‑rate calculations, and reconstructed wear‑loss values for BM and LW‑DED samples in XY and Z orientations. Porosity analysis – stitched optical/SEM images, binary masks, porosity maps, and numeric summaries of area fractions. SEM/BSE microstructures – high‑resolution micrographs for BM and LW‑DED samples, including etched and polished states. EDS point analyses and maps – raw spectra, quantified compositions, and visual elemental maps. EBSD measurements – .ctf or .ang files, grain‑size distributions, phase maps, IPF maps, misorientation data, and boundary character distributions. XRD measurements – raw diffractograms and phase‑identification results. All files are organized in a clear folder structure with documentation to ensure transparency and reproducibility. File formats include CSV, TXT, TIFF/PNG, XLSX, PDF, and instrument‑specific formats (Bruker, JEOL, Oxford/EDAX). A README file describes the structure and content of each subfolder. This dataset is released under an open license to support reproducibility, secondary analysis, and use in future research on Fe–Co–Ni alloys, high‑thermal‑conductivity tooling materials, and directed energy deposition processes.
