Phase equilibria of the Au–In–Sn system have been investigated by Differential Scanning Calorimetry (DSC), metallographic examination, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) measurements. The 130 ∘C isothermal section of the phase diagram was studied. The ternary diagram shows six three-phase fields, and one ternary Au4In3Sn3 phase, which melts incongruently at 382 ∘C and shows a homogeneity range between 21 and about 30 at.% In, at constant Au/Sn ratio.The DSC results have been combined with microstructural observations and thermodynamic modelling [G. Cacciamani, G. Borzone, A. Watson, Thermodynamic modelling and assessment of the Au–In–Sn system, CALPHAD 33(1) (2009) 100–108] and seven invariant reactions have been identified.
