Paper Abstract

Cast metal matrix composites produced by stir casting method have cost advantages over the composites made by other techniques. In this study, the influence of TiB2 volume fraction on microstructure and mechanical properties of Al-TiB2 composites has been investigated. Three different volume fractions (5, 10, and 15) of particulate TiB2 were used in production of aluminum matrix composite at 750°C. Microstructure of the composites was studied by Scanning Electron Microscopy (SEM). Composition of the samples was analyzed by X-ray diffraction (XRD). The mechanical properties of the specimens (hardness and tensile strength) were also measured. Experimental results show that the microstructure is remarkably affected by TiB2 addition level. The mechanical properties were considerably improved by addition of TiB2 particles.
