Fabrication and Characterization of Al 6063/Tio2/B4c Hybrid Composite by the Electromagnetic Stir Casting Processes

Abstract

A composite material is composed of two or more physically and chemically different phases having better properties than these individual components. Reinforcements are typically distributed over continuous matrix components. If the matrix is metal, the composite is called a metal matrix composite (MMC). A new hybrid composite is developed using the aluminium (6063) alloy and the reinforcements TiO2 (Titanium Dioxide) and B4C (Boron Carbide) by Electromagnetic Stir Casting Process. This research work focuses on the production of different combinations of aluminium matrix composites with 2% to 12% weight percentage of reinforcements. At this weight%, B4C is 1% to 6% and TiO2 is 1% to 6%. After completing the fabrication process, various mechanical properties like tensile strength, impact strength, and hardness were analyzed to determine the effect of reinforcements. The developed composite material exhibits excellent tensile strength and hardness. Tensile strength increased from 110MPa to 190.8MPa. The hardness increased from 60BHN to 83BHN however the impact strength decreased from 20Joule to 12Joule
