The primary objective of this paper is to present and discuss the appropriateness of using the stir casting process as a viabke approach for the fabrication an in-situ aluminum alloy-based metal matrix composite (MMCs). The exothermic chemical reaction that occurs between the K2TiF6 and KBF4 salts is responsible for the formation and presence of the reinforcing titanium diboride (TiB2) particles in the melted aluminum-copper alloy. Presence of these particles exerts an influence on hardness, tensile strength and even ductility of the engineered composite material. With the help of X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) both the chosen aluminum alloy and the synthesized aluminum alloy composite material were characterized to facilitate a better understanding of the intrinsic morphological details and/or intrinsic features to include the size, morphology and distribution of the TiB2 reinforcement in the aluminium alloy metal matrix. For purposes of enhancing the mechanical properties of the chosen Al-4.5 pct. Cu alloy and the Al-4.5 wt.pct Cu/xTiB2 composite a T6 heat treatment sequence was used and test results of the heat treated alloy compared with results obtained for the as-cast counterpart.
