Carbon-nanotube-reinforced Zr-based bulk metallic glass composites and their properties

In this paper, we systematically report the preparation of carbon-nanotube (CNT)-reinforced Zr-based bulk metallic glass (BMG) composites. The physical and mechanical properties of the composites were investigated. Compressive testing shows that the composites still display high fracture strength. Investigation also shows that the composites have strong ultrasonic attenuation characteristics and excellent wave absorption ability. The strong wave absorption implies that CNT-reinforced Zr-based BMG composites, besides their excellent mechanical properties, may also have significant potential for applications in shielding acoustic sound or environmental noise.
