In this project, Aluminium metal matrix hybrid composites are processed through stir casting methodology. A356 is reinforced with ceramic particle-like Titanium diboride (TiB 2 ) and Tungsten carbide (WC) in varying weight percentages of 92.5% A356 and TiB 2 5% WC 2.5% of Sample 1, A356 90% TiB 2 5% WC 5% of Sample 2, A356 100% of Sample 3 through stir casting technique. Under the Vickers hardness test, the Sample consisting of 90% A356 + 5% TiB 2 + 5% WC exhibited superior results. Under the Tensile test, the Sample of 90% A356 + 5% TiB 2 + 5% WC exhibited higher tensile strength when compared with the remaining two Samples. It is because the ceramic reinforcement particulates are harder than the A356 matrix material. Then the fractured Samples were examined under SEM and fracture mechanisms were studied.
