Abstract
This study explores the advancement of aluminum-based composite manufacturing by leveraging tungsten carbide (WC) reinforcement through the stir casting technique. Aluminum alloy served as the matrix material, enriched with ceramic reinforcement particles. The alloy underwent complete melting in a muffle furnace, maintaining a temperature of about 700°C. Ceramic particles were methodically introduced into the molten alloy, ensuring homogeneous dispersion through continuous stirring at 400 rpm for 10 minutes. The resulting composite exhibited a uniform distribution of WC particles, seamlessly integrated throughout the alloy matrix. Remarkably, the addition of 7% WC reinforcement led to substantial enhancements in mechanical properties: a 22.67% improvement in tensile strength, a remarkable 37.9% increase in hardness, a notable 25.80% enhancement in fatigue strength, and a significant 27.67% improvement in wear resistance. These findings underscore the efficacy of the stir casting technique in optimizing the properties of aluminum-based composites, offering promising avenues for the development of high-performance materials for diverse engineering applications.

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
