The effect of alloy composition on the glass forming ability (GFA) of the Ca-rich Ca-Mg-Zn alloys has been investigated. In a wide composition range of 10 % - 30 % Zn and 5 % - 25 % Mg bulk metallic glass (BMG) samples with the diameter larger than 1 mm are fabricated by conventional copper mold casting method and injection casting method in air atmosphere. Among the alloys investigated, the Ca65Mg15Zn20 alloy exhibits the highest GFA enabling to form BMG sample with the diameter of at least 15 mm. The σ parameter has better correlation with Dmax in the Ca-Mg-Zn alloys than previously suggested parameters such as ΔT X, Trg, K and γ parameters.
