Abstract
This paper was focused on significantly increasing the ductility and strength of as-cast CNTs/AZ91D nanocomposites by solid solution (T4) and aging treatment (T6). The CNTs/AZ91D nanocomposite fabricated by permanent gravity casting assisted with ultrasonic processing was subject to as-cast, T4 and T6 treatment and the mechanical properties were tested. The results showed that the ductility and the tensile strength of the nanocomposites after T4 treatment were increased by 23.8 percent and 82.8 percent compared with the as-cast properties. After T6 treatment, the tensile strength and especially the yield strength of the nanocomposites was increased by 26.2 and 17.6 percent, while its ductility was still increased by 20.7 percent. The strengthening and toughing mechanisms of the nanocomposites were discussed based on the microstructure characterization results.
