The role of solidification conditions on the microstructural features of AA6111 aluminum strips cast on a horizontal single belt caster
Bibliographic record
Abstract
Abstract The effect of the thickness of strips and cooling rates on the macro- and micro-structural features such as grain size, secondary dendrite arm spacing, and intermetallic phases, were studied for AA6111 aluminum alloy cast on a simulator of a horizontal single belt strip casting process. Different strips were investigated. As strip thickness decreased from 2.49 mm to 0.55 mm, the grain size decreased about 56 % and secondary dendrite arm spacing decreased about 56.7 %. An equation was developed based on the results obtained via thermal analysis which relates secondary dendrite arm spacing to cooling rate in this process. The formation and behavior of various complex intermetallic compounds in AA6111 were studied using scanning electron microscopy. The compositions of the precipitates were analyzed using electron probe microanalysis and their most likely stoichiometries determined.

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.
