Miedema model based methodology to predict amorphous-forming-composition range in binary and ternary systems

Abstract From the earlier works on the prediction of amorphous forming composition range (AFCR) using Miedema based model and also, on mechanical alloying experiments it has been observed that all amorphous forming compositions of a given alloy system falls within a linear band when the chemical contribution to enthalpy of the solid solution (ΔH ss ) is plotted against the enthalpy of mixing in the amorphous phase (ΔH amor ) . On the basis of this observation, a methodology has been proposed in this article to identify the AFCR of a ternary system that is likely to be more precise than what can be obtained using Δ H amor  − Δ H ss
