- Abstract
Fabrication of particle-reinforced aluminum matrix composites has been pursued with a keen interest recently. However, a comparison of the effect of different reinforcements on the mechanical properties and wear resistance of A356 matrix composites fabricated by FSP is of great interest to be considered. In the present work, the microstructural, mechanical, and wear properties of A356 matrix composites reinforced by SiC, TiC, ZrO, and BC particles are investigated. Moreover, the effect of pin profile on distribution of reinforcing particles in the stir zone of the FSPed specimens is investigated. Hardness and wear tests are performed in order to investigate mechanical and wear properties of the composites. The composite reinforced by TiC particles exhibits higher hardness value compared with other reinforcements due to the excellent bonding between TiC and metal matrix as well as higher hardness value of reinforcement itself than other reinforcements. Moreover, wear test results show that the wear resistance of the composite is significantly improved compared with that of the base metal.
