“…Fig. 2 shows the calculated enthalpy of mixing of the liquid and the hcp solid solution phases in comparison with CALPHAD assessments [50][51][52][53][54][55][56]. It should be mentioned here that the maximum solubility of Ca in hcp Mg is lower ( o1.0 at%) than those of the other alloying elements considered (43.0 at%); the CALPHAD assessment and also the 2NN MEAM values are (L1 2 ) 3.39…”

“…Table 4 and Fig. 1 show the calculated enthalpy of formation of stable compounds and various hypothetical metastable (or unstable) compounds of well-known simple structures, in comparison with experiments and other calculations [20,[45][46][47][48][49][50][51][52][53][54][55][56][57][58][59], for each binary system. The calculated enthalpy of formation values for stable compounds (C14-Mg 2 Ca, C1-Mg 2 Sn, A12-Mg 24 Y 5 , C14-Mg 2 Y and B2-MgY) are atom E i f (eV), surface energy γ suf (mJ m À 2 ), stacking fault energy γ sf (mJ m À 2 ), thermal expansion coefficient ε (10 À 6 K À 1 ), specific heat C p (J gram-atom À 1 K À 1 ), melting point T m (K), heat of fusion ΔH m (kJ gram-atom À 1 ) and fractional volume change on melting ΔV m /V solid (%).…”

“…NayebHashemi and Clark [239] along with others like Egan [254], Eckert et al [255], Pavlova and Poyarkov [256] optimized the phase diagram using measured thermodynamic data. Very recently, Jung and Kim [257], Meng et al [258] and Kang and Pelton [259] optimized the same system and modeled the liquid phase by the MQM. They considered the thermodynamic data reviewed by Nayeb-Hashemi and Clark [239].…”

Magnesium-based alloys are becoming a major industrial material for structural applications because of their potential weight saving characteristics. All the commercial Mg alloys like AZ, AM, AE, EZ, ZK, and so forth series are multicomponent and hence it is important to understand the phase relations of the alloying elements with Mg. In this work, eleven essential Mg-based binary systems including Mg-Al/Zn/Mn/Ca/Sr/Y/Ni/Ce/Nd/Cu/Sn have been reviewed. Each of these systems has been discussed critically on the aspects of phase diagram and thermodynamic properties. All the available experimental data has been summarized and critically assessed to provide detailed understanding of the systems. The phase diagrams are calculated based on the most up-todate optimized parameters. The thermodynamic model parameters for all the systems except Mg-Nd have been summarized in tables. The crystallographic information of the intermetallic compounds of different binary systems is provided. Also, the heat of formation of the intermetallic compounds obtained from experimental, first principle calculations and CALPHAD optimizations are provided. In addition, reoptimization of the Mg-Y system has been done in this work since new experimental data showed wider solubility of the intermetallic compounds.

“…Similarly, the In-Mg and In-Sn binary systems and the Mg-In-Sn ternary system were critically evaluated and optimized in our previous work [97] by using the MQMPA as well for the liquid phase. In order to construct a self-consistent thermodynamic database of Mgbase system, the thermodynamic parameters reported for the [30] N/A Ag-In Moser et al [47] , Liu et al [91] N/A Ag-Sn Oh et al [98] N/A In-Mg N/A Wang et al [97] In-Sn Liu et al [91] Wang et al [97] Mg-Sn Meng et al [99] Jung et al [95,96] Mg-Sn-Ag N/A N/A Mg-Sn-In N/A Wang et al [97] Mg-Ag-In N/A N/A Sn-Ag-In Liu et al Mg-Sn, [95] In-Mg, [97] In-Sn, [97] and Mg-In-Sn [97] systems were thus used in the present work for the optimization of the whole Mg-Sn-Ag-In quaternary system.…”

Phase equilibria in the Mg-rich region of the Mg-Sn-Ag ternary system were determined by quenching experiments, differential scanning calorimetry, electron probe micro-analysis, and Xray diffraction techniques. No ternary compounds were found in the studied isothermal sections. A critical evaluation of the available experimental data and a thermodynamic optimization of the Mg-Sn-Ag-In quaternary system were carried out using the calculation of phase diagrams method. The modified quasichemical model in the pair approximation was used for the liquid solution, which exhibits a high degree of short-range order. The solid phases were modeled with the compound energy formalism. All available and reliable experimental data were reproduced within experimental error limits. A self-consistent thermodynamic database was constructed for the Mg-Sn-Ag-In quaternary system, which can be used as a guide for Mg-based alloys development.
