Au-Ni-Sn Ternary Phase Diagram Evaluation - SpringerMaterials This report for the ternary system Au-Ni-Sn discusses binary systems, solid phases, invariant equilibria, liquidus surfaces, isothermal sections, temperature-composition sections, thermodynamics, and materials properties and applications. For an in-depth review see: Au-Ni-Sn Phase System Bibliography Report. Microstructural and Diffusion Analysis of Au-Sn Diffusion ... Au-Sn phase diagram is shown in Fig. 1. Two eutectic points are located in both tin-rich and gold-rich regions. For most conventional solder, the eutectic Au-Sn compositions are used in high reliability applications especially the gold-rich composition [8-10]. In this phase diagram, there are many varieties of IMC phases [11, 12].

The Au Sn phase diagram - ScienceDirect The resulting proposed Au Sn phase diagram contains six intermetallic compounds and seven invariant reactions. Within the gold-rich region of the diagram there are four invariant reactions that occur: peritectics at 532 and 521 °C, a eutectic at 280 °C and a peritectoid at 190 °C, below which ζ ′ is stable. The solubility range of tin in the ζ phase at 280 °C is 9.5-17.6 at.
