“…1) was very carefully determined by Owen and Roberts (8) over the entire temperature range; their results are in good agreement with those of Hume-Rothery (4) and of Weibke and Eggers (3), so that this part of the system can be considered as well established, but in the composition range 23 to 40 atom % indium, the data of the previous investigations (3,6) are in conflict in several respects.…”

In the system Ag-In, the isothermal phase transformation at 281 "C previously assumed by Weibke and Eggers has been found not to exist. Metastability of they phase and of the indium phase is persistent at room temperature. The boundaries of the intermediate phases have been redetermined. At room temperature, the equilibrium y phase (hexagonal) exists between 71.0 and 70.3 % silver. At 325 "C and higher temperatures, the y-phase region extends to higher indium concentrations than those given by Weibke and Eggers. The order-disorder transforn~ation of the y phase, postulated by Hellner, does not appear to exist. The liquidus is found to lie approximately 8 "C higher than that determined by Weibke and Eggers.At room temperature, the E phase exists between 67.5 and 65.0% silver. At these compositions, the cubic cell edges of the E phase are o = 9.878 + 0.004 and 9.887 0.004 A, respectively. The y/(y + E) phase boundary has been redetermined and extended.A new a' phase is claimed to exist at approximately 73.8 wt. % silver. It is formed by a peritectoid phase reaction at 187". In the a' phase the silver atoms occupy the face-centered positions and the indium atoms, the corner positions of the cubic lattice. The intensities of diffraction lines were calculated using such a model and were found to be in reasonable agreement with the observed intensities of the a' phase. The cell edge of the a' phase is 4.144 + 0.004 A, at room temperature, and this is identical, within experimental error, with that of the a phase.A new phase diagram for the Ag-In system has been constructed.

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 kinetics of intermetallic compound (IMC) formation in thermally evaporated Ag-In bilayers, with In on top of Ag, was investigated using X-ray diffractometry, applied to the surfaces of the bilayer specimens, as well as scanning electron microscopy, applied to cross-sections of the bilayer specimens, prepared by a focused ion beam instrument. IMC formation was followed at room temperature as well as at elevated temperatures of 50 °C, 60 °C, and 70 °C. Two distinct growth regimes were observed coinciding with the availability of pure In. The AgIn2 IMC nucleated initially, followed by nucleation of the Ag2In IMC. The growth of AgIn2 was found to be controlled by both diffusional processes as well as interfacial reactions. The growth of the Ag2In IMC is dominantly diffusion-controlled. An interdiffusion coefficient of D=1.1±3.9·10−4 cm2 s−1 exp(−60.5±9.2 kJ mol−1R−1T−1) was obtained for the Ag2In IMC. The observations were discussed in terms of the interplay of thermodynamic and kinetic constraints.
