Mechanical properties and wear resistance of nano Al/SiC composites fabricated via APB

Abstract In this study, Nano AA1100/SiC composites have been fabricated via accumulative press bonding (APB) on the AA1100/SiC composited which have been stir casted. Then, the effect of silicon carbide particles on the mechanical properties, wear resistance and microstructural evolution of these composites have been investigated. To study the effect of Nano SiC Wt.% and as its novelty, all the stir casted samples went under cumulative press bonding process after four cycles to guarantee a uniform distribution of reinforcement particles through the aluminum matrix. The experimental results showed that the strength of these composites were enhanced and the elongation of samples decreased by higher SiC Wt.% contents. Also, there is a significant growing in wear resistance by increasing of SiC content into the Al matrix through stir casting process.
