Abstract

fetched live from OpenAlex

The 3D microstructure of a second-generation single-crystal nickel-based superalloy , René N5, has been analyzed using laboratory-based X-ray diffraction contrast tomography (lab-based DCT). This experiment has demonstrated the precise capabilities of lab-based DCT in resolving subgrain boundaries with a misorientation angle of less than 1°, achieving an angular accuracy as fine as 0.1°. The performance of the lab-based DCT has been compared with standard and widely used electron backscatter diffraction (EBSD) analysis. Obtaining the 3D microstructure non-destructively enabled the segmentation of the network of nickel-based single-crystal dendrites, opening up new opportunities for studying crystal mosaicity.

Teacher imitation

Not 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.
