“…So far, a quaternary alloy 84Sn-3Ag-3Bi-10In (in wt.%) seem to be the best alternative among the selection of Pb-free solder systems [5]. In line with that, in recent years there has been quite a few thermodynamic studies on phase diagrams of four ternary systems (Ag-Bi-In [6,7], Ag-Bi-Sn [8,9], Ag-In-Sn [10,11] and Bi-In-Sn [12,13]) that make a quaternary Ag-Bi-In-Sn system.…”

“…In their study Sabbar et al [6] determined enthalpy of formation for alloy samples with compositions along six isoplethic sections x(Bi):x(In)=1:4, x(Bi):x(In)=1:2, x(Bi):x(In)=1:1, x(Bi):x(In)=62:38, x(Ag):x(Bi)=1:3 and x(Ag):x(In)=1:1 in a temperature range 809 to 911 K using a high temperature microcalorimeter. As a result, the enthalpy of formation of liquid can be correctly represented by the Toop relation over the entire ternary molar fraction range.…”

“…The ternary Ag-Bi-In system has been previously investigated by Sabbar et al [6], Vassiliev et al [7], Liu et al [14] and Kameda and Yamaguchi [15].

Considering possible applications and scarceness of literature data, Ag-Bi-In system was investigated in terms of microstructure, mechanical and electrical properties of ternary alloys from an isothermal section at 100 °C. Based on the experimentally obtained results hardness and electrical conductivity of all ternary alloys from the ternary Ag-Bi-In system at 100 °C were predicted. In addition, the selected isothermal section was further thermodynamically assessed and experimentally studied using scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), X-ray powder diffraction (XRD) analysis and light optical microscopy (LOM). Phase transition temperatures of alloys with overall compositions along vertical sections x(Ag)=0.5 as well as liquidus temperatures were experimentally determined by DTA. The experimentally obtained results were compared with literature data and with the results of thermodynamic calculation of phase equilibria based on CALPHAD method and corrected data for Ag-In binary system. Calculated liquidus projection, invariant equilibria and phase diagram of the Ag-Bi-In ternary system are presented as well.

“…The results suggest that the enthalpy of mixing is slightly temperature dependent, especially for higher In concentrations and temperatures close to the liquidus line. Korhonen and Kivilahti, [3] Moser et al, [9] and Sabbar et al [10] assessed the experimental data and presented an optimized version of the thermodynamic parameters; however, they did not take into account the temperature dependence of the enthalpy of mixing.…”

The partial and integral enthalpies of mixing of liquid Ag-In-Sn and Ag-In-Pd-Sn alloys were determined at 900 °C by a drop calorimetric technique using a Calvet-type microcalorimeter. The binary interaction parameters of Ag-In and the ternary interaction parameters of Ag-In-Pd and Ag-In-Sn were fitted based on both literature data and the authors' measurements employing the Redlich-Kister-Muggiano model for substitutional solutions. Furthermore, it was investigated whether additional quaternary interactions have to be taken into account for the description of the enthalpy of mixing in the Ag-In-Pd-Sn system.

“…There is limited thermodynamic work on the Ag-In-Bi metal system. 9,10 No stable ternary phases have been discovered. The lack of a ternary phase and the immiscibility of Ag and Bi (illustrated by the Ag-Bi phase diagram 10 ) simplify the thermodynamics of the system.…”

Solid–liquid interdiffusion is a metallurgical bonding technique, suitable for assembly of temperature sensitive materials. We identify Ag-(In-Bi) as meeting the low-temperature bonding requirements, theoretically as low as 73°C. This work focuses on understanding the bonding process and the interactions between the metal elements. Ag-(In-Bi) was bonded using an eutectic In-Bi foil at both 150°C and 180°C. The resulting bondlines were layered as Ag/Ag9In4/AgIn2/In-Bi compounds/AgIn2/Ag9In4/Ag. At some sections the phase growth of AgIn2 or Ag9In4 bridged the bond. Because of this bridging of γ-Ag9In4, temperature stability of ~480–570°C, is readily possible. The majority of the remaining Bi was located within large pockets near the middle of the bondline, and the minority as precipitates in protruding arms. Mechanisms for these Bi precipitates and intermetallic arm growth are discussed, and the evidence indicates that dissolution and surface planarity play important roles in their formation.
