Low-temperature alloys for lead-free solders - Study of physico-chemical characteristics

Popis výsledku v původním jazyce

New types of lead-free solders on the base of tin with addition of metals Ag, Al, Bi, Cu, In, Mg, Sb, Zn were studied. Various alloys were experimentally prepared by smelting of metals in an inert atmosphere or in vacuum in resistance furnace. Purity of metals was minimally 4N. The specimens of solders were studied metallographically including the micro-hardness measurements, complete chemical analysis (ICP-AES, OES), X-ray micro-analysis of alloys by SEM and EDX in order to determine the composition and identification of individual phases. Significant temperatures and enthalpies of phase transformations were determined by DTA. After long-term annealing of selected alloys in vacuum followed by quenching the structural and chemical microanalyses of the present phases and their limit concentrations were carried out. The achieved results were compared with the thermodynamic modelling of the ternary systems (ThermoCalc, Pandat, MTDATA and databases CALPHAD, COST 531 and COST MP0602). Electrical resistivity, density, magnetic susceptibility and wettability of solders were measured as well. (C) 2018 Web Portal IOP. All rights reserved.
