Abstract: The Al-Mg-TiB2 is noteworthy modern Aluminum-based composite material due to its phenomenal mechanical properties. These composites show a solid interface between supports – grid when contrasted with other customary Aluminum composites. A blended salt course system was utilized to plan in-situ Al-Mg-TiB2 composites in the present examination. Al – xTiB2 (x = 0, 2.5, 5, 7.5 wt. percent) Metal-Matrix Composites were produced utilizing K2TiF6 and KBF4 salts utilizing an exothermic procedure at 800°C. The materials have been portrayed utilizing SEM and EDS to affirm that no Al3Ti has been created, which is the benefit of blended salt course innovation. SEM micrographs showed TiB2 particles that are conveyed homogeneously without agglomerations all through the aluminum lattice. Research has additionally been directed to examine the hardness of the amalgam strengthened with TiB2 in-situ composites. The hardness of all the created composites was higher than that of Aluminum combination framework in light of the development of TiB2 which brought about grain refining activity.
