Abstract

Mg–6Zn/1.5%SiC nanocomposites were successfully fabricated by ultrasonic cavitation-based dispersion of SiC nanoparticles in Mg–6Zn alloy melt. As compared to un-reinforced Mg–6Zn alloy matrix, the mechanical properties of the nanocomposites including the tensile strength and yield strength of the Mg–6Zn/1.5%SiC nanocomposites were significantly higher; the good ductility of Mg–6Zn alloy matrix was retained. Nanoparticles were dispersed well though there were still some SiC microclusters in the microstructure. Also, the grain size of Mg–6Zn alloy was reduced considerably by the addition of 1.5%SiC nanoparticles.
