中文摘要	Based on the consideration of the liquid phase stability, the resistance to crystallization and the glass transition enthalpy, a new criterion Q. defined as ((T(g) + T(x))/T(l)).(Delta E/Delta H), where the T(g), T(x), T(l), Delta E and Delta H are the glass transition temperature, the onset crystallization temperature, the liquidus temperature, the crystalline enthalpy and the fusion enthalpy, respectively, has been proposed for evaluating the glass-forming ability of bulk metallic glasses. The new criterion Q exhibits better correlation with the maximum cross section thickness (D(m)) for glass formation compared with gamma (=T(x)/(T(l) + T(g))), T(rg) (=T(g)/T(l)) and Delta T(x) (=T(x) - T(g)) respectively. The available data from literatures and experiments have confirmed the effectiveness of the newly developed criterion. (C) 2010 Elsevier B.V. All rights reserved.
