Abstract

In the current study, a characteristic has been carried out on the influences of Zirconium dioxide (ZrO2) content and casting temperature on mechanical properties and fracture behavior of AA6063 Al/ZrO2 composites. AA6063 aluminum extrusion Metal Matrix Composites (MMC) reinforced with 5, 10 and 15 vol % ZrO2 were fabricated at various casting temperatures, viz. 750, 850 and 950oC via the stir casting method. Based on the acquired results, optimum amount of reinforcement and casting temperature were measured by evaluating the density and mechanical properties of the elements. Hardness and tensile tests were carried out in order to find the mechanical properties of the elements. Fracture surfaces of the samples were also studied to find the main fracture mechanism(s) of the elements. The results indicate that all samples fractured due to the structure interdendritic cracking of the matrix extrusion. Reinforcing the Al matrix extrusion with ZrO2 molecules, improved the hardness and ultimate tensile strength of the extrusion to the maximum values of 70 BHN and 232 MPa, respectively. Hence, the highest mechanical properties were obtained by the specimen including 15% of ZrO2 produced at 750oC.
