Strong Grain Neighbour Effects In Polycrystals- Data Set
Bibliographic record
Abstract
3D-XRD measurements are for a commercially pure zirconium (CPZr) sample deformed in-situ to 1.2% strain. HR-EBSD measurements are for the same deformed sample after unload. Crystal Plasticity Finite Element (CPFE) simulation was done on the measured micro-structure and results of the NHS model are provided. HR-EBSD and CPFE results are generated using in-house codes. Details of the 3D-XRD codes are provided in the following link: https://sourceforge.net/p/fable/wiki/Home/ The work and further analysis of the results are described in: "Strong Grain Neighbour Effects in Polycrystal" Published in Nature Communications, DOI: <strong>10.1038/s41467-017-02213-9</strong> Other relevant papers: Abdolvand, H., Majkut, M., Oddershede, J., Wright, J., Daymond, M.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
