Effect of Ti addition on the wettability of Al–B<sub>4</sub>C metal matrix composites
Bibliographic record
Abstract
Abstract In this study, the wettability of B 4 C by molten Al, as well as Al–Ti alloys, with different Ti contents has been studied using the sessile-drop method. In general, the contact angle decreases with increasing temperature and time. The results show that an appropriate amount of Ti addition improves the wettability of B 4 C by Al. Analyses of the interfaces of solidified drops revealed that Al 3 BC and AlB 2 particles form around the B 4 C particles when they are in contact with pure Al. However, when Ti is added to Al, AlB 2 particles disappear and a new Ti-rich layer composed of TiB 2 particles forms around B 4 C surfaces. In addition, the effect of Ti addition on the surface tension of aluminum has also been examined.

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.
