Viscous flow of the Cu47-Ti34-Zr11-Ni8 glass forming alloy [PDF]

, 2000
The viscosity of the Cu47-Ti34-Zr11-Ni8 glass forming alloy was determined by beam bending experiments and by a noncontact oscillating drop technique. These viscosity data can be described with the Vogel-Fulcher-Tammann relation. Using the strong/fragile
