Abstract
The effect of Al and Zr on the viscosity of the supercooled liquid in melt-spun Zr-Ti-Nb-Cu-Ni-Al glassy ribbons has been evaluated by parallel plate rheometry. The change of composition drastically affects the viscosity of the samples. The viscosity of the supercooled liquid and the fragility parameter (D*) increase with increasing Al or decreasing Zr contents, indicating an improved glass-forming ability. At the same time, the temperature of the glass transition shifts to higher values. A clear correlation between fragility parameter and glass transition has been found. This correlation provides a guide for the estimation of D* for this particular system when the glass transition is known.
