Abstract

fetched live from OpenAlex

Zirconium alloys are of particular interest for applications within the nuclear industry given their low thermal neutron capture cross-section to strength ratios, adequate corrosion resistance, and high temperature stability. However, zirconium alloys are susceptible to hydrogen embrittlement, which limits the service lives of zirconium alloy components in reactor systems. Hydrogen charging, or hydriding, is a technique used to artificially age ex-service or as-received material to predetermined hydrogen concentrations for material testing on representative specimens. This study presents a thermo-mechanical approach to precision hydriding. Discussion on the development and commissioning of a suitable apparatus, called the Thermomechanical Hydrogen Ingression System (THIS), is provided. Hydriding results from commissioning as well as several repeatability tests are reported, which demonstrate the viability of the technique and equipment.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
