Aluminum alloy-based metal matrix composites (AMMCs) are extensively utilized due to their distinctive mechanical properties. Al-6%Si alloy was reinforced with different contents of alumina (Al₂O₃) particles (0, 1.5, 3, 4.5, 6, 7.5, 9, 10.5 and 12% wt.) and the MMCs were prepared by stir casting at 800°C. Microstructural characterization of AMMCs was studied using optical microscopy, to emphasize the homogeneous distribution of the reinforcement particles (Al₂O₃) in the Al alloy matrix. Hardness and wear tests were used to study the influence of Al₂O₃ addition on the mechanical properties of the prepared composites. The interpolation method is applied as a perfect alternative approach for saving the consumed time during the experimental work. The used mathematical expression can be utilized for an early prediction of the mechanical properties of AMMCs at different contents of Al₂O₃ particles without carrying out much experimental analysis. The current study shows that the linear interpolator is the optimal one where it achieved Mean square error (MSE) equals 0.1875, and 0.0119 for hardness and wear loss tests, respectively.
