ROJAS CHAVEZ, Hugo  y  JARAMILLO VIGUERAS, David. Comportamiento de la resistividad eléctrica en las aleaciones del sistema Pb-Sn obtenidas por aleado mecánico por compactación múltiple cerrada. Superf. vacío [online]. 2008, vol.21, n.1, pp.11-15. ISSN 1665-3521.

Mechanical alloys of 40Pb-60Sn (eutectic) and 34Pb-65Sn-1Zn (ternary) were produced through multiple closed die compaction. Differential thermal analysis (DTA) revealed melting temperatures of studied materials. A eutectic like behavior, during melting, was observed in the mechanical alloys formed, even for the first compaction cycle (cc). Electrical resistivity measurements (ρ_T) were carried out on eutectic, ternary and commercial soldering. For the eutectic MA, an increase in the electrical resistivity of 54% was observed, when compared to commercial soldering. For the ternary alloy such increase was 69%.
