“…An extrapolation of the Henrian activity coefficient in their study gives ln c 0 Mg ¼ À1:52 at 1873 K (1600°C), which is a little lower than found in the present study. A recent thermodynamic optimization of the system by Jung et al [33] gives ln c 0 Mg ¼ À1:74 at 1873 K (1600°C), which is in very close agreement with the present work.…”

The distributions of calcium and magnesium between silicon and CaO-MgO-SiO 2 slags have been determined in the present study at 1873 K (1600°C). The distribution equilibria were used to estimate the activities of the slag components in the binary CaO-SiO 2 and MgO-SiO 2 systems. These activities were used to determine the Henrian activity coefficients of calcium and magnesium in liquid silicon at 1873 K (1600°C). The distribution equilibria were also used to estimate the activity of SiO 2 in the ternary CaO-MgO-SiO 2 system. Finally, the activities of CaO and MgO were estimated in the ternary CaO-MgO-SiO 2 system using the determined Henrian activity coefficients in liquid silicon together with the distribution equilibria and the estimated activities of SiO 2 .

“…Detailed TEM SAD analysis indicates that Mg 2 Sn and Si phases have the same crystal structure with only a small difference in the lattice parameters, they can form a completely miscible structure. 23,24) However, inter-solution of these phases has not been found in the present study. Further study is necessary to understand the exact formation mechanism of these particles.…”

A study has been made on the effect of Sb and Sr on the microstructure and mechanical properties of Mg-Sn-Al-Si based (TAS) alloy. When Sb is added to TAS alloy, the morphology of second phase particles changes to fine radial shape by the formation of nucleation cores. Refined microstructure of TAS-Sb alloys results in higher yield strength and larger elongation with lower creep resistance than those of TAS alloy. Sr addition induces the formation of large amount of thermally stable second phase particles. Due to the large amount of thermally stable second phase particles, TAS-Sr alloys show superior creep resistance and higher yield strength at both room and high temperatures than those of TAS alloy.

“…[26][27][28][29][30] Yan et al [26] and Kevorkov et al [27] used 6 and 4 parameters, respectively, to describe the liquid phase. Jung et al [28] modeled this system using the modified quasichemical model to describe the liquid phase, in which 4 parameters were introduced for the liquid phase. Yuan et al [29] applied an exponential formulation to describe the excess Gibbs energy of the liquid phase.…”

Based on the critical review of the available experimental phase equilibrium data for the constituent quaternary systems in the Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni quinary systems, a set of self-consistent thermodynamic parameters for these systems has been obtained using the CALPHAD approach. In combination with the constituent binary, ternary and quaternary systems, the thermodynamic database for the quinary Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni systems was developed. Comprehensive comparisons between the calculated and measured phase diagrams and invariant reactions showed that the experimental data were satisfactorily accounted for by the present thermodynamic description. The established database was used to describe the solidification behaviors of Al alloys 6063 (Al-0.39Si-0.20Fe-0.43Mg, in wt.%) and 2618 (Al-2.24Cu-1.42Mg-0.9Fe-0.9Ni, in wt.%) under Gulliver-Scheil non-equilibrium condition. The reliability of the present thermodynamic database was also verified by the good agreement between the Gulliver-Scheil calculation and experiment.
