| Abstract: | The results show that Zr51Cu24.70Ni14.34Al9.96 bulk metallic glass has high glass forming ability(GFA) with the glass transition temperature Tg = 728 K and the reduced glass transition temperature Trg(Tg /Tm) =(0.707).The critical diameter is nearly 12 mm.But the 12 mm sample was found to contain farthing crystalline phases,including a hexagonal crystalline phase Zr5Al4(a = 8.437 nm,c = 5.8 nm) and a cubic crystalline phase Cu9Al4(a = 8.702 nm).Accordingly,reducing the content of Al can further improve the ... |
