Effect of nano Al 2 O 3 particles on the mechanical and wear properties of Al/Al 2 O 3 composites manufactured via ARB

This study first tried to fabricate AA1060/Al 2 O 3 composites via the stir casting and accumulative roll bonding process. Then, the effect of nano Al 2 O 3 Vol% on mechanical, wear, and microstructural properties of these kinds of composites have been investigated. An excellent particle distribution through the aluminum matrix has been achieved after the fourth cycle. Then, mechanical properties, wear resistance, and microstructural properties have been investigated. The results showed that the strength of these composites was enhanced and the elongation of samples decreased by higher alumina Vol% contents. Also, there is a significant increase in wear resistance by increasing alumina content in the Al matrix through the stir casting process.
