Phase equilibria and thermodynamic properties of the Au-Sb-Sn ternary system are important for the design of Au-based alloys as high-temperature lead-free solders to replace high-Pb solders. In this work, phase transition temperatures of five Sb-Sn alloys were measured using differential thermal analysis (DTA), and the temperatures of three invariant reactions were determined. Based on the measured experimental results in this work and the reported results, the Sb-Sn binary system was re-optimized using the CALPHAD method. The calculated results were in good agreement with available phase equilibria and thermodynamic data. This work was further combined with the previous assessments of the Au-Sn and Au-Sb binary systems and the present optimization of the Sb-Sn binary system to calculate the phase equilibria and thermodynamic properties of the Au-Sb-Sn ternary system, according to the reported experimental results, including thermodynamic properties and phase equilibria. The calculated liquidus projection, isothermal sections, vertical sections, as well as enthalpy of mixing and activity of Sn in liquid alloys are consistent well with the reported experimental results. A self-consistent set of thermodynamic parameters was obtained to accurately describe Gibbs energies of various phases in the Au-Sb-Sn ternary system, which would serve as a sound basis for developing a thermodynamic database of multicomponent Au-Sn-based alloy systems.

“…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.

“…[1] On the other hand, I became aware of the outstanding work of Zhangpeng Jin and Yong Du [9,10] long before I met them in person. However, the present conference booklet [11][12][13][14][15][16][17][18][19][20][21][22] displays more than a dozen important studies that Jin and more than 30 student colleagues have performed. These cover a wide range of scientific and engineering topics including amorphous Al-Fe-Zr alloys, [11] first-principles assisted assessments of Au-Co-Sn [12] and Al-Fe-Zr, [13] thermodynamics and CALPHAD modeling of TiO 2 -Y 2 O 3 , [14] B-C-Si, [15] Gd-Zn, [16] and Mg-Hg-Ga, [17] age-hardening of Ti-Al-N coatings, [18] experimental determination of Ni-Si-Zn ternary system, [19] CALPHAD study of Mg-Ag-Ca, [20] CALPHAD study of Fe-Nd-B and applications to sintering, metal spinning and levitation melting, [21] and predictions of interfacial reaction in multicomponent systems.…”

The program booklet of the 14th National Conference and Multilateral Symposium on Phase Diagrams and Materials Design contained more than 400 pages of papers devoted to the application of computational thermodynamics to the design and use of a wide variety of engineering materials. The work of Professor Jin and his students which displayed many examples of the CALPHAD method featured prominently at this meeting. My presentation illustrated examples in which thermochemical descriptions can be coupled with diffusion data to derive useful practical insight into design of alloys and amorphous and ceramic systems. The wide use of these methods will be enhanced in the future by coordinated investigation of the lattice stability of pure metals and compounds as was illustrated at the conference. Specific directions for such efforts are suggested.
