FIG. 1.

The fragility parameter D * is plotted versus the width of supercooled liquid region and for Ca-based BMGs. The inset table gives the VFT fitting parameter D *, T 0, approximated as , calculated , experimental , and . is calculated with .

FIG. 2.

The width of supercooled liquid region and as a function of the fragility parameter D * for La-based BMGs. The inset table shows the calculated , experimental , and . is calculated with . ( is obtained from personal communication.43)

Image of FIG. 3.
FIG. 3.

The correlation between the width of supercooled liquid region and fragility parameter D * (a), as well as (b) for several BMGs. was employed instead of due to easy availability. Figs. 1 and 2 validate the replacement because of the nearly commensurate expansion of temperature interval resulted in subequal slope. The dashed lines in (b) show the 95% prediction limits for this relation.
