EFFECT OF ULTRASONIC VIBRATION ON THE DIRECTIONAL SOLIDIFICATION OF SCN-3%ETH MODEL ALLOY
Bibliographic record
Abstract
The directional solidification process of SCN-3%ETH model alloy under 27.5 kHz ultrasonic vibration is studied in this paper. The results show that the interface growth is restrained because of the effect of ultrasonic vibration. The radius of curvature on the interface increases as the ultrasonic action time increase. When the ultrasonic vibration is removed from the melt, the refined cellular structure is formed. Because the impact of transient high temperature and pressure generated by the cavitation effect and stirring action of the acoustic streaming and shearing action caused by forced vibration, part of the dendrite tips are fractured. The interface growth rate decreases as the ultrasonic action time increase. Cavitation effects and high-frequency forced vibration caused by ultrasonic vibration in the melt are main reasons for interface growth rate change.

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.
