Abstract
TiB2 nanoparticles reinforced AS41A alloys were fabricated by ultrasonic assisted stir casting. The influence of ultrasonic treatment and TiB2 nanoparticles on the microstructure and mechanical properties of AS41A magnesium alloy was investigated. The results showed that the ultrasonic treatment obviously refined microstructure, thereby improving the mechanical properties of the magnesium alloys. The addition of TiB2 further increased the tensile strength slightly while maintaining the improved elongation as the ultrasound-treated matrix alloys.The ultimate tensile strength, yield strength and elongation of the obtained nanocomposites were improved by 27.4%, 43.5% and 84.6% compared with those of the as-cast matrix alloys, respectively.
