“…Since no literature values are available for the Co–Li system, the corresponding integral molar enthalpy of mixing was estimated using Miedema’s model [ 44 ] similar to Refs. [ 45 , 46 ]: where the enthalpy of solution of liquid i in liquid j at infinite dilution for a binary alloy, , is expressed as: where V i , Φ *, and n 1/3 are the parameters; P , Q , and R are the constants determined by Miedema [ 44 ]. The R/P value for liquid alloys, R * /P , was calculated by multiplying the quotient for solid alloys, R/P , by a factor of 0.73.…”

The partial and integral molar enthalpies of mixing of liquid Co–Li–Sn alloys were determined using drop calorimetry. The investigations were performed along six sections by the addition of lithium to mixtures with the compositions / ≈ 2:98, / ≈ 1:9, and / ≈ 3:17 as well as by the addition of cobalt to mixtures with the compositions / ≈ 3:17, / ≈ 1:2, and / ≈ 1:1 at a temperature of 1,173 K. The Co–Li–Sn system shows exothermic behavior of the integral molar enthalpy of mixing in the investigated concentration range. The integral molar enthalpy of mixing of liquid Co–Li system was calculated by Miedema’s model to fit our measured ternary data using an extended Redlich–Kister–Muggianu model for substitutional solutions.Graphical abstract

“…The Miedema theory provides a semiempirical model for calculating the formation enthalpy of binary alloys. 1012) Zhang et al 13,14) proposed a simple and effective method based on the improved Miedema model for calculation of formation enthalpy of crystalline and amorphous phases of ternary systems. In this study, the subregular model was used to calculate the formation enthalpy.…”

“…In the 1970s and 1980s, Miedema et al 1012) developed a semi-empirical theory that described the GFA of binary metallic glasses; however, the original model was only applied to binary transition metallic glass systems. In 2010, Zhang et al 13,14) proposed the subregular model based on the improved Miedema model to calculate the mixing enthalpy of ten IIB-IIIB binary alloy systems. The subregular model was subsequently used in the calculation of the formation enthalpy of ternary and multiple alloy systems.…”

Zr-based metallic glasses have been extensively studied owing to their high glass forming ability and superior mechanical properties. The glass forming ability of ZrNi(Al, Ti, Nb) and ZrCu(Al, Ti, Fe, Co, Ni) bulk metallic glasses was studied based on the bond parameter function and formation enthalpy model. Elliptical curves can be used to distinguish the glass forming regions from other regions in twodimensional model diagrams. The elliptic parameters can be defined by the relative parameters of the constituent elements. The reproducibilities of this model for ZrNi-and ZrCu-based metallic glasses were 84.4% and 93.4%, respectively, indicating good agreement of this model with available experimental data. The predicted results provide a new strategy for designing excellent-performance metallic glasses.
