Experimental investigation of mechanical and tribological properties of Al6061–ZrC–B<sub>4</sub>C hybrid composites
Bibliographic record
Abstract
Aluminium metal matrix composites (ALMMCs) have been widely used because of their superior properties such as high strength to wear ratio, high wear resistance, and higher heat conduction rate. The addition of reinforcements in the form of discontinuous particles leads to an increase in the properties of metal matrix composites (MMCs). In the present study, ALMMCs were fabricated with the addition of discontinuous reinforcement particles of zirconium carbide (ZrC) and boron carbide (B 4 C). The mechanical properties such as tensile strength, hardness, and impact strength were tested as per ASTM standards. The tribological properties were tested using a pin-on-disc setup under different loading conditions (10, 20, 30, 40 N). Moreover, the morphological characterisation of the ALMMCs was carried out by scanning electron microscope (SEM) analysis. Furthermore, differential thermal analysis (DTA) and thermogravimetric analysis (TGA) were performed to find the thermal stability of the ALMMCs. The findings show that variations of reinforcement of ZrC added gave improved properties such as hardness, tensile strength, impact strength, and wear resistance.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
