Abstract
Abstract Combination of metal matrix materials with carbon quantum dots (CQDs) can not only optimize the property of metal matrix materials, but also produce novel material systems with ultra-high performance or superior comprehensive performance. The excellent electrical, mechanical, and thermal characteristics of CQDs can compensate for some intrinsic defects of the metal matrices to improve the composite properties. The various interfaces formed through the different degrees of CQDs dispersion in the metal matrices are essential in the mechanism of the composite performance improvement. In this review, the research progress and results of CQDs in metal matrix composites are discussed and summarized, including the recent preparation methods of CQDs and carbon nanostructure-reinforced metal matrix materials, as well as the influences of the preparation methods on the material structures and properties. In addition, by focusing on the interfaces between CQDs and metal matrices in composite materials, the performance improvement and reinforcement mechanisms of the CQD-modified metal matrix composites are described from mechanical, electrical, and thermal aspects. Further studies on CQDs in metal matrix composites are still required to provide theoretical guidance for the preparation of CQDs-reinforced metal matrix composites with intensity and ductility above the average.

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
