Abstract

A new Ca-Mg-Zn alloy having significantly improved glass forming ability (GFA) has been developed. The ternary Ca65M15Zn 20 bulk metallic glass (BMG) with diameter of at least 15 mm is successfully fabricated by conventional copper mold casting method in air atmosphere. The measured critical cooling rate (Rc) for glass formation in the cone-shaped copper mold is less than 20K/S. The Rc has been calculated from an integrated transformation curve constructed by combining continuous cooling transformation (CCT) and continuous heating transformation (CHT) curves. The calculated Rc is in good agreement with the measured value.
