抄録

The new Cu-based bulk glassy alloys in Cu–Zr–Ti–Sn–Si alloy system were formed by copper mold casting. The critical diameter for glass formation is 5 mm for Cu₅₀Zr_42.5Ti_7.5, and increases to 6 mm for (Cu_0.5Zr_0.425Ti_0.075)₉₉Sn₁ and 7 mm for (Cu_0.5Zr_0.425Ti_0.075)_98.8Sn_0.6Si_0.6. The minor addition of Sn or Sn and Si in Cu₅₀Zr_42.5Ti_7.5 causes an increase in the supercooled liquid region from about 40 K to about 50 K, and in the reduced glass transition temperature from about 0.59 to about 0.60.
