摘要：

Cu-Zr-Ti-Sn bulk metallic glasses were produced by copper mold casting. The effects of Sn addition on glass-forming ability (GFA), thermal stability of the Cu60Zr30Ti10 bulk metallic glass were investigated. It was found that a bulk metallic glass of 5 mm in diameter was prepared in a (Cu60Zr30Ti10)(99)Sn-1 alloy by copper mold casting. The addition of 1 at.% Sn is effective for an increase in GFA. The DeltaT(x) and T-g/T-I are 46 K and 0.63, respectively, for (Cu60Zr30Ti10)(99)Sn-1 alloy. With increasing the content of Sn, the value of TITI increases, but the alloys begin to lose bulk metallic GFA. The new parameter gamma has a better correlation with the GFA of the Cu-based alloys.
