Thermodynamic calculation on this model deduces a parameter describing the glass forming ability of metallic alloys: a_c=(1-2.08/φm)T_g/ T_m, where T_g is glass transition temperature, T_m is the melting temperature, and φm is entralpy change of melt-ing. It is believed that easy glass forming alloy systems have larger values of a_c This new criter-ion of GFA not only provides the theoretical background for several GFA criteria in the litera-ture cited, but also can predict the GFA of many alloy systems more reasonably and accurately.
