A range of new magnesium-based bulk metallic glasses (BMGs) from the Mg-Ag-Ca, Mg-Cu-Ca ternary and Mg-Ag-Cu-Ca quaternary alloy systems have been discovered using the effective radius ratio method. These alloys are located over a broad composition range from (at.%): Mg - 38-76, Ag - 0-38, Cu - 0-36 and Ca - 7-27, some of which are located far from ternary eutectic reactions. Here, we report the alloy design method, critical casting size and thermophysical properties of these new BMGs.
