“…Recently, thermodynamic descriptions of many binary and ternary systems including Au-Pb, Au-Al, Au-In, Au-Zn binary systems and Au-Ag-Si, Au-Ag-Sn, Au-Bi-Sb, Au-Ge-Sn, Au-Ge-Sb, Au-Ge-Si, Au-Ag-Pb, Au-In-Sn, Au-In-Sb, Au-Si-Sn and Au-Co-Sn ternary systems have been developed by Wang, Liu and Jin [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] using the CALPHAD method [27,28]. Thermodynamic database of the corresponding binary and ternary systems has been established on the basis of their assessments.…”

a b s t r a c tThermodynamic optimization of the Au-Sb binary system was updated as well as the Si-Sb binary system was assessed thermodynamically using the CALPHAD method based on the critical review of the available experimental information from the published literature. The solution phases including liquid, fcc A1(Au), diamond A4(Si) and rhombohedral A7(Sb), are modeled as substitutional solutions and their excess Gibbs energies are expressed by a Redlich-Kister polynomial. The solubility of Si in the intermetallic compound AuSb 2 is not taken into account because of the lack of experimental information. Combined with previous assessment of the Au-Si binary system, thermodynamic modeling of the Au-Sb-Si ternary system was performed to reproduce well the measured phase equilibria. The liquidus projection and several vertical sections of this ternary system were calculated, which are in reasonable agreement with the reported experimental data.

“…The literature [10][11][12][13][14][15][16][17][18][19][20] contains reports on thermodynamic calculations for various Au-based alloy systems, including Au-Ag-Si, Au-Ag-Pb, Au-Ge-Ni, Au-Si-Sn, Au-Bi-Sb, Au-Ge-Cu, Au-Ge-Sn, Au-Ag-Sn, Au-In-Sn, Au-Sb-Si, and Au-Ge-Sb. Despite this extensive coverage, there appears to be a lack of reported data on the thermodynamic calculations for the Au-Ge-In, Au-Ge-Si, and Au-Ge-Zn ternary systems.…”

In this study, the CALPHAD approach was employed to model the thermodynamics of the Au-Ge-X (X = In, Sb, Si, Zn) ternary systems, leveraging experimental phase equilibria data and previous assessments of related binary subsystems. The solution phases were modeled as substitutional solutions, and their excess Gibbs energies were expressed using the Redlich–Kister polynomial. Owing to the unavailability of experimental data, the solubility of the third elements in the Au-In, Au-Sb, and Au-Zn binary intermetallic compounds was excluded from consideration. Additionally, stable ternary intermetallic compounds were not reported in the literature and, thus, were not taken into account in the present thermodynamic calculations. Calculations of liquidus projections, isothermal sections, and vertical sections for these ternary systems have been performed, aligning with existing experimental findings. These thermodynamic parameters form a vital basis for creating a comprehensive thermodynamic database for Au-Ge-based alloys, which is essential for the design and development of new high-temperature Pb-free solders.
