Abstract
The variation of compressive load displacement curves and fracture modes of Zr-based bulk metallic glass (BMG) composites with increasing carbon nanotube (CNT) addition was investigated in detail. The interfacial reaction between the added CNTs and the glass matrix causes the formation of some v-shape nicks on the CNTs. These nicks have significant effect on the mechanical properties of the BMG composites. The compressive fracture strength increases with increasing CNT addition at first, and start to decrease gradually with further increasing the CNT addition when the volume fraction of the CNT addition is more than a critical value. The fracture modes of the BMG composites also change from typical shear flow deformation behavior to completely embrittling fracture gradually. The v-shape nicks formed in the interfacial reaction is responsible for the reducing fracture strength.
