Ternary and binary alloys with different ratios of Ag, Al, Bi, Cu, In, Mg, Sb, Sn and Zn were prepared experimentally. The following characteristics were studied: temperatures and enthalpies of phase transformations (DTA, TG, DSC), macro-and micro-structural analysis, micro-hardness, chemical analysis, X-ray and density measurements and electrical resistivity of selected solders, test of wettability with or without use of fluxes, measurement of corrosion properties.
