Abstract

The Zr₅₀Cu₅₀ binary bulk metallic glasses were prepared using cooper mold casting. The effects of cooper mold temperature and protective gas on the glass-forming ability were studied. The cooling rate of alloy melt was controlled by cooper mold temperature and protective gas properties. Compared with Ar, He as protective gas speeds up the cooling rate, at the same time, it can improve the smoothness of alloy samples surface under ultra low temperature. The fully amorphous alloy with diameter of 2.5 mm can be cast for Zr₅₀Cu₅₀ by using He as protective gas and liquid nitrogen as cooling medium under ultra low temperature environment (79 K). The size of Zr₅₀Cu₅₀ binary bulk metallic glasses exceeds the maximum dimension of 2 mm.
