Spreading Mechanism of Molten Al-Alloys on TiC Substrates
Bibliographic record
Abstract
The contact angle data drawn from sessile drop tests of commercial aluminum alloys (1010, 2024, 6061 and 7075) on TiC substrates (at 900 °C, under vacuum and argon atmospheres) was plotted on a logarithmic time scale. Several aspects were taken into account to describe the spreading mechanism in four kinetic stages in systems that exhibited wetting (1010, 2024 in both environments and 7075 under vacuum). It was found that commercial multi-element alloys do not improve wetting of Al on TiC and that alloying elements and the atmosphere exert a significant role on the wetting behavior in the early stages. A physical model describing spreading in the early stages is presented. The influence of alloying elements and the type of atmosphere on the deoxidation of the drops are discussed.

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.
