Abstract

In this paper, the effect of graphene oxide (GO) nanoplates on the strengthening mechanism of Al6061-GO nanocomposites have been investigated. To make composite samples, GO nanosheets with various weight percents of 0.0, 0.2, 0.5, and 0.8% were added to the molten Al6061 through the stir casting method. Then the cast composite slabs were hot rolled. Tensile test was used to study the mechanical properties of composite specimens. The experimental results showed that the nanoplates of GO have strong strengthening effects along with increase in ductility in the fabricated composites. To model the strengthening effect of GO in Al6061 matrix, the modified shear-lag and the modified Zhang-Chen strengthening mechanisms have been utilized. Comparisons between the model predictions and the experimental results revealed that both models can satisfactorily predict the yield strength of fabricated nanocomposites.
