The current study is an attempt made to synthesize nano B4C/Graphite reinforced AluminumZincMagnesium alloy composites by altering the weight %age of B4C (2%, 4%, and 6%). SEM was used to examine the morphology and mechanical behaviour was done in accordance with ASTM standards (ASTM E8, E9, E23, and D790). The microstructure displays a nearly uniform dispersion of reinforcement particles in the matrix alloy, with no residual pore visible. From the XRD analysis it is identified that interfacial phases between the base material and ceramic strengthening particulates are identified as Al 3 BC, AlB 12 , Mg 2 Si, SiAl 2 and it strive as strengthening mechanism of synthetic composites. The interfacial phases identified as Al 3 BC, AlB 12 , Mg 2 Si, and SiAl 2 , and serve as a strengthening mechanism for synthetic composites, according to XRD. When compared to the base material, intermixtures had higher hardness (28.07%), ultimate tensile strength (69.31%), compressive strength (18.58%). The flexural strength is improved (29.32%) due to higher dislocation density in the matrix and wider variations in the elastic modulus. The impact strength improved significantly (72%) due to a reduction in porosity and grain refinement.
