Properties of new gold based multicomponent alloys as innovative lead-free solder material

Abstract

The results of experimental investigation of some thermal, structural, mechanical and electrical properties of selected alloys in the In–Ga70Au10Sb20 cross-section of Au–Ga–In–Sb system are presented in this paper. Applied experimental techniques included: differential scanning calorimetry, light optical microscopy, scanning electron microscopy with energy dispersive spectroscopy, hardness, microhardness and electrical conductivity measurements.

Keywords:

• In–Ga70Au10Sb20 alloys
• Lead-free solder
