Abstract

fetched live from OpenAlex

Abstract Using ultrasonics, the acoustic characteristics of Cu 45 Zr (45– x ) Hf x Ag 10 ( x = 0–25) glassy alloys were examined in terms of complex elasticity. The values of bulk modulus ( K ), Lamè parameter ( λ ), Young's ( E ) and shear ( G ) moduli of Cu 45 Zr (45– x ) Hf x Ag 10 glassy alloys are found to have a unique order for metallic materials, except for polymers. The large Poisson ratio (∼0.421) and the lower G / K ratio (∼0.167) at 25 at% Hf indicate rubbery characteristics that readily undergo uniaxial volume‐preserving deformation but resist three‐dimensional nonvolume‐preserving deformation. The complex dynamic viscosity shows that visco‐elasticity of the glassy alloys is dominated by shear motion. The large peaks in K and λ , and small ones in E and G at 5 at% Hf, and one large peak in the shear attenuation coefficient at 2.5 at% Hf, may indicate atomic morphological change by electron‐transverse phonon coupling.

Full frame distilled prediction

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.
