Abstract

fetched live from OpenAlex

A luminum alloys are important technological materials primarily due to their attractive strength-to-weight ratio. They are used in diverse applications ranging from packaging to the aeronautical industry. Important candidates for such applications are the alloys from the 5000 series whose primary alloying element is Mg. They may be rolled into thin sheets and offer significant strength. However, their plastic deformation at room temperature is discontinuous, with the strain localizing in narrow bands that leave undesirable traces on the surface of the final product. This is the signature of the Portevin–Le Chatelier (PLC) phenomenon, which manifests itself in certain ranges of temperature and strain rate. The repeated strain localization is due to the negative strain rate sensitivity (SRS) of the material, which, in turn, is correlated with smaller scale phenomena associated with interactions between solute and dislocations, referred to as dynamic strain aging (DSA). The technological goal is to increase the SRS to positive values in the range of temperatures and strain rates relevant for industrial processes. This would ensure material stability during processing and would eliminate the PLC phenomenon. In particular, in Al-Mg alloys, it is desirable to increase the SRS and to eliminate the PLC effect at room temperature.

Teacher imitation

Not 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.
