| Abstract: | The Cu（Zr） - based bulk metallic glass（BMG） alloy with the composition of Cu48Zr52-x Alx（x = 6, 7, 8, 9, 10, at%）was prepared in an arc furnace and formed in a copper mould. The Cu48Zr44Al9 and Cu48Zr43Al cylindrical rods consisting of single glassy phase were successfully obtained. The structural characteristic of three kinds of bulk metallic glasses was performed by XRD and the glass forming ability of them was studied by means of DSC. The results show that Cu48Zr43Al9 has the best glass forming ability and thermal stability. |
