Thermodynamic modelling and assessment of the Au–In–Sn system

As part of COST Action 531, a thermodynamic assessment of the Au–In–Sn has been carried out using experimental phase equilibrium data from the literature, along with more recent and more extensive experimental results from phase equilibrium and thermodynamic studies. As well as reproducing the experimental data very well, the self-consistent thermodynamic description produced for this ternary system is consistent with the COST 531 thermodynamic database for lead-free solders. Assessed thermodynamic parameters for the system are listed, along with crystallographic details of all stable phases.
