摘要：
The effects of mold preheating temperature on the glass-forming ability of Zr(64.9)Al(7.9)Ni(10.7)Cu(16.5) and Zr(47)Cu(37.5)Ag(7.5)Al(8) alloys are investigated using traditional copper mold casting. It is found that there exists an optimum mold temperature for glass-forming alloy systems. For the two Zr-based alloy systems studied the optimum mold temperature is 353 K. This is explained from the perspectives of heat transfer efficiency and the wettability between liquid alloy and copper mold.
