Abstract
Techniques and strategies to characterize the damping properties of high-damping metals from two of the major classes of damping mechanisms are described. Two types of high-damping metals were chosen for the study: a series of die cast zinc-aluminum alloys that exhibit predominantly amplitude-independent, thermally activated damping mechanisms and a manganese-copper (Mn-Cu)-based alloy casting that exhibits pronounced amplitude-dependent damping together with thermally activated damping. It is shown that the damping behavior of the zinc-aluminum alloys can be described semi-empirically over the ranges of temperature and frequency useful in practical applications. In contrast, a similar description of the damping behavior of the Mn-Cu alloy is not possible because of the change in amplitude-dependent damping with frequency and the variation of damping with microstructural changes from place to place in the casting.

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
