Dependence of glass forming ability on liquid fragility: Thermodynamics versus kinetics

摘要: The dependence of glass forming ability on liquid fragility is studied with thermodynamic and kinetic analyses. A general expression the Gibbs free energy difference between an undercooled its equilibrium crystal presented to address thermodynamically effect formation. It found that increasing favors formation, remarkably contrasting from point view. dependences in metallic alloys molecular isomers are compared, kinetics thermodynamics formation are, respectively, emphasized.
