Physics-augmented synthetic microstructure and crystallographic texture dataset for extruded magnesium alloys: 101,000 representative volume elements

This dataset contains 101,000 synthetic representative volume elements (RVEs) spanning 15 extruded magnesium-alloy classes. Each RVE is provided as a 300 × 300-pixel, 8-bit RGB PNG orientation map, organised by alloy class. The folder also contains class-level orientation anchors and the script used to create 1,015 horizontally mirrored samples. The RVEs were generated with DREAM.3D-NX from experimentally grounded grain statistics and crystallographic texture distributions. The augmentation starts from 119 measured processing conditions across 17 alloy classes; two heat-treated classes are not included in the final RVE dataset. The associated Acta Materialia manuscript describes the synthesis, validation, orientation encoding and use of these RVEs for generative inverse design. Scope: This deposit contains the synthetic RVE folder only. It does not contain the original experimental micrographs, measured tensile curves, synthetic ODF files or crystal-plasticity simulation results.
