Correlation between average melting temperature and glass transition temperature in metallic glasses

The correlation between average melting temperature (< T-m >) and glass transition temperature (T-g) in metallic glasses (MGs) is analyzed. A linear relationship, T-g=0.385 < T-m >, is observed. This correlation agrees with Egami's suggestion [Rep. Prog. Phys. 47, 1601 (1984)]. The prediction of T-g from < T-m > through the relationship T-g=0.385 < T-m > 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 T-g.
