“…25 The observed ternary alloys showed positive deviation from the ideal molar volume. A similar effect was observed for the activity of Zn ternary alloys: 22 over the whole range, there were positive deviations. However, for the alloys with X Sn /X Sb ratio of 1, the variations were very small and increased with increasing Sn content in the alloy.…”

In this work, liquid Sb-Sn-Zn alloys were studied to determine their density, viscosity, and surface tension using the discharge crucible method. The measurements were carried out for alloy compositions having X Sn /X Sb ratio of 1, 3, 4, and 9 and Zn content X Zn of 0.05, 0.1, 0.2, and 0.7 in the temperature range from 550 K to 1050 K. The effect of the Zn concentration in the Sb-SnZn alloys on their density, viscosity, and surface tension was observed. Over a wide temperature range, the viscosity and surface tension increased with increasing Zn content in the alloy, while the density decreased. The experimental results obtained for surface tension and viscosity were compared with the results of the Butler model for surface tension and with the MoelwynHughes, Sichen-Boygen-Seetharaman, Seetharaman-Sichen, Kozlov-Romanov-Petrov, and Kaptay models for viscosity.

“…The works dealt with the phase diagram of the Sb-Sn-Zn system, [10] structure of Sb 2 SnZn intermetallic phase [11] and metal activities in ternary liquid. [12] Some older sources [10,13,14] reported studies of the Sb-Sn-Zn system on account of the use of the ternary intermetallic phase Sb 2 SnZn as a semiconductor. An important milestone of material research of alloys was the CALPHAD method developed in 1975 [15] which was further developed (extended-generalized-adopted) for alloys.…”

International. This e-offprint isExperimental Study of the Sb-Sn-Zn Alloy System ONDREJ ZOBAC, JIRI SOPOUSEK, JIRI BURSIK, ADELA ZEMANOVA, and PAVLA ROUPCOVA The Sb-Sn-Zn alloy was prepared and researched by experimental methods, which allow obtaining information on the thermodynamic stability of the coexisting phases. Thermal analysis was used to determine the phase transition temperatures of experimental alloys. Equilibrium composition of coexisting phases after long-term temperature equilibration was determined by electron microscopy. The existence of one ternary stoichiometric phase Sb 2 SnZn was experimentally confirmed by diffraction technique. The CALPHAD method for prediction of the phase diagram of the Sb-Sn-Zn system from binary subsystems was used in this work.

“…The RoHS directive banned the use of Pb in solder joints, and every few years expands to another group of materials, including materials for the supervision and control, and medical devices. Numerous lead-free solders studies have been conducted in recent years (Ref [1][2][3][4][5], and focused on the solders with a melting point below 473 K, which can replace low-melting eutectic Sn-37Pb (wt.%). As a Pb-free replacement, Sn-based alloys such as: Sn-Ag-Cu and Sn-Zn, which have properties similar to the Pb-Sn eutectic alloy, have been proposed.…”

Solders for ultrahigh-temperature applications were defined by Vianco as those able to sustain working conditions with temperatures as high as 573 K, with momentary temperature rise up to 623 K. Zn-Al eutectic alloy (12 at.% Al) fits such defined criteria with respect to its melting temperature. It was found that small additions of indium to Zn-Al eutectic lower its melting temperature. The aim of this work is to assess if and to what extent thermal properties and wetting behavior are affected. It was found that addition of In increases electrical resistivity and coefficient of thermal expansion value. Wetting angles on Cu and Al substrates of liquid Zn-Al eutectic-based alloys containing up to 1.5 at.% of In were studied with the sessile drop method, after wetting at 773 K in the presence of flux. A decrease of apparent wetting angle was observed with increasing concentration of In. After wetting tests solidified alloy-substrate couples were crosssectioned and examined with scanning electron microscopy coupled with electron dispersive X-ray analysis.
