Electrolytic Production of Aluminum Using Mechanically Alloyed Cu–Al–Ni–Fe-Based Materials as Inert Anodes
Bibliographic record
Abstract
materials with varying from 0 to 20 (wt %) were prepared by mechanical alloying. For , the as-milled was made of an α-phase, whereas was formed at . Upon consolidation, a small amount of κ Ni/Fe-rich Al phase with a B2 structure is formed for and 10, whereas no new phase is formed in the other compounds. Aluminum electrolysis tests conducted at an anode current density of for 20 h in a low temperature electrolyte showed that the electrode stability and aluminum purity are strongly dependent on the alloy composition. The lowest values of cell voltage (4.1 V) and Cu contamination (0.8 wt %) were obtained for . This relatively lower contamination is due to the formation of a dense and adherent oxide scale between the outermost oxide layer and the substrate. In comparison, a hot-rolled C63000 commercially available alloy with the same composition but lower chemical/microstructural homogeneity gave a higher Cu contamination level (1.4 wt %).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
