Thermodynamic prediction of glass forming range in Al-Mg-REM ternary system

Abstract

The glass forming range of the ternary Al-Mg-REM (Rare Earth Metal) system has been explored and predicted. T-o curves, thermodynamically calculated, have been compared with T-g which has been approximated as crystallization temperature, T-x. From an empirical kinetic relationship with the formation enthalpy, T-x was obtained. Predictive calculations have not been directly verified by experiments but this approach may be used as a useful guide to predict the glass forming range of ternary and even multicomponent systems.
