The successful fabrication of bulk glassy alloys depends on the chemical composition and fabricating process. To prepare bulk metallic glasses (BMGs) by casting with copper mould, the cooling ability of the mould and the melting temperature are considered. In this work the influence of the melting temperature on the fabrication of the BMGs is studied by varying the suction casting temperature of the Ti44.10Cu.37.04Zr9.80Ni7.06Sn2.00 alloy by varying the current density employed in melting process. The results show that there is an optimum melting temperature range for fabricating the Ti-Cu-Zr-Ni-Sn BMG by suction casting. When the temperature is outside this range, the crystalline phases occur within the glassy matrix. The influence of the melting temperature on the fabrication of the Ti-Cu-Zr-Ni-Sn BMG is discussed.
