EBSD Dataset of the Alpha and Beta Phase Orientations for a Hot-Rolled Zr-2.5Nb Alloy

A set of ex-situ electron backscatter diffraction (EBSD) datafiles following rolling of a Zr-2.5Nb alloy at seven different temperatures (700C to 900C) and three rolling reductions (50%, 75%, 87.5%). Data for annealing (750C for 2 hours) and rolling from a different starting texture is also included, with beta-phase orientations reconstructed from alpha phase data. The dataset was created by Christopher Stuart Daniel at the University of Manchester and accompanies a 2019 paper in the Journal of Alloys and Compounds.

Use Cases

• Modeling crystallographic texture changes based on rolling temperature and reduction parameters mentioned in the description.
• Analyzing alpha-beta phase orientation relationships using the reconstructed beta-phase data.
• Training machine learning models to predict microstructural evolution from processing conditions like temperature and annealing time.
• Validating software for phase reconstruction based on the Burgers orientation relationship described.

Strengths

• Includes data for seven specific rolling temperatures (700C, 750C, 775C, 800C, 825C, 850C, 900C) and three specific rolling reductions (50%, 75%, 87.5%).
• Contains additional data for annealing at 750C for 2 hours and rolling from a different 'as-forged' starting texture.
• Provides reconstructed high-temperature beta-phase orientations derived from alpha phase data using a defined crystallographic relationship.

Limitations

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