Description:
The reduced glass transition temperature (Trg) and fragility index (m) are both used to predict the critical cooling rate (Rc). When either Trg or m is individually used to predict log10(Rc), a large deviation occurrs in the prediction of log10(Rc) because both of the corresponding correlations have low coefficients of determination (R2). The R2 value increases from either 0.33 (by using only Trg) or 0.68 (by using only m) to 0.91 by using both Trg and m. Therefore, the glass‐forming ability (GFA) is estimated more accurately when Trg and m are both applied to predict log10(Rc) through a binary linear regression analysis.
