FIG. 1.

(Color online) Transient isothermal viscosity relaxation of Alloy 1 (Fe58Co6.5Mo14C15B6Er0.5) measured at three different temperatures: 743, 753, and 763 K.

FIG. 2.

(Color online) Equilibrium viscosity data for various Fe-based bulk-glass-forming liquids. Lines are fits to the data using Eq. (2). Arrows designate glass-transition temperatures, based on a viscosity value of 1012 Pa·s.

FIG. 3.

(Color online) Angell fragility plots for various metallic bulk-glass-forming liquids. Experimental viscosity data and associated fits for liquids other than the Fe-based are taken from Ref. 17.
