Abstract
Two base matrixes of Al–15 vol.-%B4C and 6063–15 vol.-%B4C metal matrix composites (MMCs) were produced using a powder injection technique. Alloying element additions of 0·5 wt-%Ti, 0·35 wt-%Zr and 0·35 wt-%Sc were added to the base matrixes to produce various alloy compositions of Al–15 vol.-%B4C and 6063–15 vol.-%B4C MMCs. The production route of the MMCs used in the current project was the molten metal processing technique using powder injection. For the purpose of investigating the reinforcement (B4C)/matrix (Al) interaction, five alloy compositions of pure Al–15 vol.-%B4C and 6063–15 vol.-%B4C with various additions of Ti, Zr and Sc were produced. A metallic L shaped mould was used for casting the aluminium MMCs. Reinforcement/matrix interface interactions in the produced composites were investigated, using a field emission gun scanning electron microscope and energy dispersive X-ray techniques, as a function of alloying element addition.

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
