Zircaloy-4 Deformation Data for Irradiated and Non-Irradiated Samples

University of Manchester researchers provide HRDIC, EBSD, and image data for Zircaloy-4 samples, both non-irradiated and proton irradiated to 0.1 dpa, deformed to approximately 3% strain. The dataset supports a 2021 publication in the Zirconium in the Nuclear Industry symposium proceedings. It includes a Jupyter notebook for analysis using the open-source DefDAP Python package.

Use Cases

• Quantifying strain heterogeneity based on high-resolution digital image correlation (HRDIC) data
• Identifying active slip systems by comparing experimental slip trace angles with theoretical angles from EBSD data
• Analyzing the effect of loading direction (rolling vs. transverse) on slip and twinning activity
• Validating material deformation models against quantitative slip system activation data for irradiated Zircaloy-4

Strengths

• Data is directly linked to a peer-reviewed publication in an ASTM International symposium, providing academic context
• Includes multiple correlated data types: HRDIC, EBSD, and image data for comparative analysis
• Covers both non-irradiated and irradiated (0.1 dpa) conditions, enabling controlled comparison

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
