Abstract

The mechanical behavior of the WC particulate (WCp) reinforced Cu47Ti33Zr11Ni6Sn2Si 1 bulk metallic glass (BMG) matrix composites has been examined. The mechanical properties are improved with increasing WCp content up to 20 wt%. The ultimate compression strength and plastic strain of the composite containing 20 wt% WCp are 2.4 GPa and 2.4%, while those of the monolithic BMG are 1.6 GPa and 0%, respectively. The multiple shear band formation and crack deflections through WC particles have been identified as the main mechanism for the improved toughness.
