Effect of the substitution of Ag and Ni for Cu on the glass forming ability and plasticity of Cu60Zr30Ti10 alloy

The effect of the substitution of Ag and Ni for Cu on the glass forming ability (GFA) of Cu60Zr30Ti10 alloy has been studied. Although the substituted elements have a positive heat of mixing with Cu, the GFA was enhanced substantially in the Cu40Ni5Ag15Zr30Ti10 alloy, enabling the fabrication of a 6 mm diameter glassy rod. The plasticity improved only when Ag was substituted with Cu in a limited composition range.
