Abstract
Seeded dislocations have been reported to favor the formation of more stable precipitates. Herein, we have altered the precipitation sequence in an Al-Mg-Si alloy by inducing dislocations dynamically supplied through high-temperature cyclic deformation, enabling the atomic clusters to directly nucleate and precipitate as high-density β′ phase. Furthermore, the strength of the sample cyclically deformed at 180°C was significantly increased compared to that of the peak-aged sample, demonstrating that β’ phase can serve as an efficient strengthening phase. Our findings provide new insight into achieving more stable phases as the main strengthening phase in age-hardenable alloys.

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
