The correlation between average melting temperature (〈Tm〉) and glass transition temperature (Tg) in metallic glasses (MGs) is analyzed. A linear relationship, Tg=0.385〈Tm〉, is observed. This correlation agrees with Egami’s suggestion [Rep. Prog. Phys. 47, 1601 (1984)]. The prediction of Tg from 〈Tm〉 through the relationship Tg=0.385〈Tm〉 has been tested using experimental data obtained on a large number of MGs. This relationship can be used to predict and design MGs with a desired Tg.

    Based on Varshni equation, the shear elastic modulus at the glass transition temperature [G(Tg)] and the shear elastic modulus at 0 K [G(0)] were calculated from the elastic modulus measured at room temperature for various bulk metallic glasses (BMGs). The G(Tg)/G(0) ratios for various BMGs are...
