ABSTRACT: An effort was put forth in this study to construct a hybrid aluminum metal matrix composite with the goal to test its machining and mechanical properties. Reinforcing Silicon carbide and Titanium di boride are used to create a hybrid aluminium metal matrix composites. Optical microscopy was used to investigate the morphology of the composites and strengthened particle dispersion in depth. The hardness test was performed on the cast composite to determine its hardness using a Vickers hardness testing device. The hardness test results demonstrate that adding reinforcement SiC and TiB2 enhances the hardness value. However, increasing the reinforcement by up to 15% results in a decrease in hardness value. Tensile samples made from cast composite specimens of various compositions were mechanically tested. Tensile test findings show that adding reinforcement SiC to the base metal gave 20% strength to the composite, whereas adding TiB2 reduced the strength by 50 - 60%. The wear resistance behavior of TiB2 has been studied using wear test analysis. Wear testing revealed that the inclusion of TiB2 improved the wear resistance of the composite. The cast composite examples were machined with care. During a turning operation, the influence of machining parameters such as cutting speed (s), feed rate (f), depth of cut (d), and TiB2 weight % on surface roughness (Ra) was examined. The analysis of variance approach reveals that the percentage of TiB2 reinforcement is the single most significant parameter influencing surface quality, with a contribution of 38.86%. Tool wear research was performed to investigate tool wear pattern, built-up edge creation, the effect of TiB2 on tool wear, and the way these variables impact cast composite quality of the surface. TiB2 causes excessive tool wear, poor surface finish, and built-up edge development, all of which have an impact on surface quality.
