<sup>27</sup>Al and <sup>7</sup>Li spin‐echo and spin‐echo double resonance NMR applications to the study of lithium depletion and surface oxidation in Al–Li alloy
Bibliographic record
Abstract
Abstract The physical properties and the near‐surface microstructures of Al–Li alloys are known to be affected by thermo‐mechanical processes during alloy manufacture. The research reported here explored 27 Al and 7 Li spin‐echo and spin‐echo double resonance NMR to follow the structural changes that accompany lithium depletion and oxidation processes at the alloy surface. The NMR analysis generally agrees with conclusions reached previously using other analytical methods. The major oxide compound generated is Li 2 CO 3 and the minor oxide compound is LiAlO 2 , which is formed at higher temperatures. LiAlO 2 is shown to be formed in spatially confined clusters on the surface of the Li‐depleted, Al‐rich near‐surface layer. Copyright © 2001 John Wiley & Sons, Ltd.

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; a candidate call from one teacher head, not a consensus.
