Aluminum alloy A356/TiB2 In-situ MMCS have been fabricated through salt metal reaction route. In this present study the A356 alloy reinforced with TiB2 particle cast in permanent mould for different pouring temperatures, have showed that the mechanical properties (i.e. Fracture Toughness, Tensile Strength, Hardness) increased as compared to that cast in sand mould. Also, the mechanical properties of composites were found to increase with pouring temperature up to 820°C. The observation on SEM and XRD confirmed the formation of TiB2 particulates. The experimental results validated the FEA results obtained through ANSYS 13. The predictions on mechanical properties using these models are in good agreement with experimental data for both sand mold and permanent mold with different conditions.
