Abstract
Aluminum composite reinforced ceramic particles can be created through stirring process (Stir Casting) so that the molten aluminum to form a vortex as a space for the reinforced of Al2O3 particles well distributed on the aluminum melt. Engineering ceramic particles and vortex formation process will determine the distribution of particles in molten aluminum metal. Mg was added during the melting and argon was flushed to improve wetting system and protect oxidation. In this study, billet Al.6061 was combined with various percentage of Al2O3 from 5Vf % to 20Vf%. The results showed that the optimum tensile strength obtained at 10Vf % Al2O3 with the value of 190 MPa.
