Abstract
The study of the influence of temperature on the performance of admixed lubricants is important since higher densities are desired while keeping the ejection force at a reasonable level. Therefore, three lubricants admixed with iron powder were evaluated during compaction at 25, 65, and 110°C. An instrumented die permitting the measurement of the applied and transmitted pressures through the compact lead to the evaluation of the slide coefficient. This empirical parameter is related to the stress ratio and to the friction coefficient characterising the friction of the compact on the die wall. The evolution of the slide coefficient revealed a different behaviour at the beginning of compaction, where a higher shear resistance is desirable, compared with the end of compaction, which was more influenced by the amount of lubricant at the interface between the compact and the die wall. A too low shear resistance at that stage could however lead to stick–slip phenomenon.

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
