AB  - In this study, the phase diagram of the ternary Ag–Bi–Ge system was thermodynamically assessed and experimentally investigated, which to our knowledge has not been previously done. Differential thermal analysis (DTA), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS) and X-ray powder diffraction (XRD) were applied in order to experimentally assess three vertical sections and two isothermal sections at 200 °C and 400 °C of the Ag–Bi–Ge system. Results of the SEM–EDS and XRD analysis revealed existence of (Ge), (Ag) and (Bi) solid solution phases and absence of any ternary phases. Crystal structures of the identified phases and their corresponding lattice parameters were determined by XRD technique. Phase transition temperatures, including liquidus, solidus and temperature of an invariant reaction, were determined by means of DTA. Thermodynamic calculation of the Ag–Bi–Ge ternary phase diagram was carried out on the basis of optimized thermodynamic parameters for the constitutive binary systems acquired from the literature. Calculated liquidus projection of the Ag–Bi–Ge system and the determined invariant reactions are presented in the study as well. A close mutual agreement between the experimental results and the calculated phase equilibria was obtained.

AB  - 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.

AB  - Theoretical calculation and experimental investigation of the isothermal section of a ternary Bi-Cu-Ga system at 100 oC are presented in this paper. Thermodynamic binary-based calculation of the isothermal section was performed using Pandat software. Experimental investigation included microstructural analysis carried out using light optical microscopy (LOM) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), phase composition analysis using X-ray diffraction (XRD), Brinell and Vickers hardness testing and electrical conductivity measurements. In total, thirty alloy samples with compositions along three vertical sections Bi-CuGa, Cu-BiGa and Ga-BiCu were studied. The obtained experimental results support the calculated phase regions of the isothermal section at 100 oC. Hardness of individual phases as well as hardness and electrical conductivity of the studied alloys were measured. Based on the experimentally obtained results iso-lines of Brinell hardness and electrical conductivity along the whole compositional range were calculated by using appropriate mathematical models.
