Effects of intermetallic particles on cavitation during superplastic forming of aluminium alloy
Bibliographic record
Abstract
An Al-4.6%Mg-1.5%Mn-0.27%Fe alloy was specially processed with friction stir processing followed by cold rolling. Half of the sheet thickness contains a large number of blocky or irregular-shaped Al 6 (Mn,Fe) coarse intermetallic particles, while the other half, smaller and more spherical ones. The particle-induced cavitation upon uni-axial tension at 475°C with 2 × 10 −4 –2 × 10 −2 s −1 strain rates was investigated. The density of nuclei for cavities was estimated based on quantitative image analysis of the particles, and the strain controlled growth rate, calculated assuming the cavities are nucleated before or in the early stage of straining. The number, size and morphology of intermetallic particles are found to control the cavitation by determining the nucleation rate, but the strain controlled growth rate appears unaffected.

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.
