摘要	A modified indicator of the glass forming ability (GFA) from the previous gamma = T-x/(T-l + T-g) for various glass forming liquids is proposed based on a conceptual approach which combines more acceptable physical metallurgy views in terms of the time-temperature-transformation diagrams. It is found that the glass forming ability for glass forming liquids is closely associated mainly with two factors, i.e. (2T(x) - T-g) and T-l (wherein T-x is the onset crystallization temperature, T-g the glass transition temperature, and T-l the liquidus temperature), and could be predicated by a unified parameter gamma(m) defined as (2T(x) - T-g)/T-l. This approach is confirmed and validated by experimental data in various glass forming systems including oxide glasses, cryoprotectants and metallic glasses, which all shows a higher reliability when their glass forming ability is predicted by the modified parameter.
