Damping Behavior of Nano-sized SiC Particulates Reinforced AZ61 Magnesium Matrix Composites Prepared by High-energy Ultrasonic

Ling Lishibao, Yan Hong, Hu Zhi(Institute of Advanced Forming & Manufacturing and Die & Mold, Nanchang University, Nanchang, China)  
Nano-sized SiC particle reinforced AZ61 magnesium matrix composites SiCp/AZ61 was prepared by a self-developed high-energy ultrasonic device, and microstructure and damping behavior of the prepared composites were investigated by OM (optical microscope) and SEM (scanning electron microscope). The results reveal that SiCp particles can be uniformly and dispersedly distributed in the magnesium alloy melt by high energy ultrasonic. The damping behavior of the composites is greatly superior to that of AZ61 matrix alloy at room temperature, which is attributed to G-L dislocation-pinning theory. Interface slipping at high temperature can be easily conducted due to SiCp increasing the quantities of grain-boundaries of matrix alloy, resulting in the significant improvement of damping behavior of the composites.
