Abstract
Although used and studied since the beginning of the century, the mechanical properties of aluminum-based structural hardening alloys still conceal some secrets that metallurgists are trying to uncover. In this work we are interested in aluminum alloys and more particularly in an Al-Cu alloy. The main objective of this work was to study the influence of structural hardening heat treatments on the evolution of the mechanical and structural properties of B206 alloys. For that, we used several experimental methods adapted to this kind of scientific work. We quote essentially: the thermal treatments of setting in hardening, as well as measurements of the hardness. The analysis of the experimental results obtained by these methods allowed us to explain and to affirm that Al-Cu alloys do not give appreciable structural hardening; because of the difficulty of diffusion of iron and silicon which influences the treatment and brought in a general way to the precipitation of the phase β; plays an important role in the evolution of the mechanical characteristics of Al-Cu 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
