Abstract

fetched live from OpenAlex

Abstract This paper describes a new manufacturing process for producing functionally graded ceramic‐metal composites with anisotropic properties for thermal management in automotive engine blocks. These composites are elaborated by producing a porosity gradient within an alumina matrix, subsequently infiltrated by a molten aluminum alloy. The interconnected macro porosity inside the ceramic is controlled by the coalescence of PMMA (PolyMethylMethAcrylate) spherical particles during the elaboration step of an organic frame template in which bridges are created at contact points between the particles. The diameter of the interconnection contact plays a key role because it greatly controls the microstructure of the final composites and consequently the thermal conductivity. A numerical model was developed for simulating the different steps of the elaboration process of the composites. Numerical assessments of the effective thermal conductivity are achieved in order to examine interconnection contact effects. To end up, the developed model is validated by comparing the numerical predictions with experimental measurements.

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.
