| Abstract | Starting from CU60Zr30Ti10, the compositional dependence of bulk metallic glass (BMG) formation was revisited in the Cu-Zr-Ti ternary system. It was revealed that the optimal BMG-forming composition is located at CU60Zr33Ti7, for which a monolithic BMG rod 4 mm in diameter can be fabricated using copper mold casting. This composition is along, although slightly off, the univariant eutectic groove for the reaction (L --> Cu8Zr3 + Cu10Zr7). With respect to the corresponding Cu-Zr binary alloys, Ti has a significant effect on further stabilizing the liquid, thus increasing the glass-forming ability. For the Cu60Zr40-yTiy (3 <= y <= 10) series BMGs, the glass transition temperature T. decreased with increasing Ti content, at a rate of about 2.8 K/at.%. Among these BMGs, significant compositional dependence of compressive plasticity is not observed, irrespective of the T. change. CU60Zr33Ti7 glass exhibits maximum fracture strength around 2160 MPa. |
