Phase equilibria investigation and characterization of the Au-In-Sb system

Abstract

The Au-In-Sb system is of great interest recently, because its alloys belong to the group of potential lead-free solder materials to be used in electronics, while as a part of Au-ln-Sb-Te system, it presents a suitable phase change material in optical recording media. The results of phase equilibria investigation and characterization of the alloys in the AuIn-Sb section of the Au-In-Sb system are presented in this paper. The investigations were performed using different experimental methods - thermal analysis, optical microscopy and SEM-EDX, hardness and electrical conductivity measurements, and also, using ThermoCalc software based on adequate thermodynamic calculation.
