The use of high-energy ultrasound to prepare SiC particulate reinforced AZ61 Mg-based composites was conducted. The results show that high-energy ultrasound can make nano-ceramic particles effectively dispersed in the magnesium alloy melt. The tensile strength and yield strength increase compared with the Mg based. The particle sizes of the SiC are 100 nm, 5 μm and 20 μm, respectively. The composite materials adding 1%SiC can get better performance. Their tensile strength are respectively 321,276 and 206 MPa, elongations are 13.8%, 13.6% and 10.6%.
