3D EBSD Data of Alpha-Beta Phase Orientations in a Hot-Rolled Zr-Nb Alloy

A 3D electron backscatter diffraction dataset captures the alpha and beta phase orientations in a model Zircaloy-4 with 7 wt.% Nb alloy after hot-rolling. The data comprises 441 sequential slices, each 0.1 μm thick, measured using a plasma focused ion-beam scanning electron microscope. Christopher Stuart Daniel from the University of Manchester created this dataset, which is accompanied by a 3D reconstruction and analysis published in Acta Materialia in 2021.

Use Cases

• Analyzing 3D crystallographic texture evolution based on the indexed alpha and beta phase orientations.
• Training models for microstructure segmentation based on the 441 sequential EBSD slices.
• Validating 3D reconstruction pipelines based on the provided DREAM.3D software output.
• Studying phase distribution and grain morphology in hot-rolled Zr-Nb alloys based on the grain-averaged data.

Strengths

• Contains 441 sequential EBSD slices, providing detailed 3D spatial resolution.
• Includes a fully reconstructed 3D volume generated using a custom DREAM.3D pipeline.
• Data is associated with a peer-reviewed publication in Acta Materialia (2021).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
