摘要：Cu-based Cu-Zr-Al metallic glass samples with diameters of more than 10 mm could be produced in a composition range of 45 to 52 (at. pct) Cu, 41 to 47 at. pct Zr, and 6 to 10 at. pct Al by a copper mold casting method. The best glass-forming ability was obtained for the Cu47Zr45Al8 alloy, and the glassy sample with a diameter of 15 mm was fabricated. The minor addition of Ag or Dy can enhance the glass-forming ability of the Cu47Zr45Al8 alloy, which decreases the liquidus temperatures, leading to increase in the reduced glass transition temperature. Fully glassy samples with diameters up to 20 mm were obtained for a (Cu0.47Zr0.45Al0.08)(98)Dy-2 alloy.
