Abstract

To synthesize a crystalline-glass composite in a Cu-based bulk metallic glass, the monotectic reaction was used. The (Zr-Sn-Pb)-rich crystalline phase was found to coexist with the (Cu-Ti-Ni)-rich glassy phase during the process of quenching from the melt in the (Cu47Ti33Zr 11Ni6Sn2Si1)100-x+Pb x=1,2 system. Microstructures consisting of uniformly dispersed crystalline particles in the amorphous matrix were observed by scanning electron microscope (SEM) and transmission electron microscope (TEM). Compressive tests demonstrated that the fracture strain of the sample with a Pb content of 1 at% was three times higher than that of the sample with no Pb.
