Evaluation of electronic transport and premature failure in the melt-spun Pb-Sn-Sb-Ag rapidly solidified alloys

PbSn30Sb7Agx (where x = 0, 0.5, 1.0, 1.5, 2 and 2.5 wt%) melt-spun alloys were prepared by a melt spinning technique. The dynamic mechanical properties of the as-casted and prestressed alloys were measured. Furthermore, the electron transport properties were evaluated by measuring the electrical resistivity of the rapidly solidified alloys. The studied alloys can be found in stable mechanical configuration up to prestressed value of 1.75 GPa which we recommend for the use as an ultimate value for these alloys. Prestressing alloys can also deteriorate their resistivity.
