Abstract
Understanding the deformation mechanism of aluminum alloys is very important for the transportation and aerospace industries. In the present study, the flow stress-strain curves for AA2024 aluminum alloy were obtained by compressive tests performed on Gleeble-3500 thermo-mechanical machine at temperatures from 250 to 450 °C, strain rates from 0.01 to 10 s-1. The dynamic recrystallization (DRX) kinetics was analyzed and the flow stress model characterizing dynamic recrystallization for AA2024 aluminum alloy was put forward. The flow stress curve at elevated temperature was described as three stages, i.e. hardening, softening and stable stages. The characteristic parameters for dynamic recrystallization in the flow stress model were described as function of Zener-Hollomon parameter. By analyzing the dynamic recrystallization region of flow stress curve, the kinetics of dynamic recrystallization was revealed.

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 it
