AZ31 Magnesium Alloy: High-Resolution Digital Image Correlation Data for Deformation Study

High-resolution digital image correlation data from a study of AZ31 magnesium alloy deformation. The data was collected by Alberto Orozco‐Caballero at the University of Manchester using a FEI Magellan HR 400L FE-SEM, producing mosaics covering 135x120 µm². It includes correlation data in text and binary formats, a high-resolution shear strain image, and companion EBSD data available via separate DOI.

Use Cases

• Quantifying strain localization and deformation incompatibility based on the high-resolution shear strain image.
• Validating micromechanical models using the correlation data from before and after deformation mosaics.
• Correlating deformation behavior with microstructure using the companion EBSD dataset mentioned in the description.

Strengths

• Includes data from two mosaics, one before and one after deformation, enabling direct comparison.
• High-resolution images with speckle sizes in the 20-40 nm range, captured using a specific FE-SEM model and settings.
• Correlation data is provided in both human-readable (.txt) and binary iPython (.npy) formats.

Limitations

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