dc.description.abstractA new composition region of bulk metallic glass formation, around Cu52Zr40Ti8, was discovered in the Cu-Zr-Ti ternary system, for which monolithic bulk metallic glass rods of 4 mm in diameter can be fabricated using copper mold casting. The solidification of the Cu52Zr40Ti8 deeply-undercooled liquid mainly undergoes a univariant eutectic reaction, (L → Cu10Zr7 + CuZr), even though this composition was predicted to be a ternary eutectic point (L → Cu10Zr7 + CuZr + Cu2ZrTi) by CALPHAD calculations. With respect to the deep-eutectic reaction of (L → Cu10Zr7 + CuZr) in the Cu-Zr binary alloys, alloying of Ti has a significant effect on further stabilizing the liquid, as indicated as a drop of the univariant eutectic groove, limiting the coupled growth of two crystalline phases, hence increasing the glass-forming ability. © 2008 Elsevier B.V.
