Study of electrical conductivity and hardness of the alloys of ternary Bi-Sb-Zn system and calculation of isothermal section at 298 K

Abstract

Considering the importance of the lead-free solders, alloys of ternary Bi-Sb-Zn system were characterized by microstructural SEM-EDS and optical microscopy analysis, Brinell hardness tests and electrical conductivity measurements. Isothermal cross section at 298 K was calculated using CALPHAD method and PANDAT 8.1 software package. The phases on calculated cross sections were found to be in a good agreement with experimentally determined phase compositions in analyzed microstructures.
