Phase equilibria in the ternary In-Ni-Sn system at 700 °C

► The In-Ni-Sn system was studied experimentally (SEM, EPMA, XRD) in the entire composition range at 700 °C. ► A full isothermal section at 700 °C was established based on the experimental results. ► Solid solution ranges of ternary phases were characterized using SEM, EPMA and XRD. ► The isotherm at 700 °C was calculated using the CALPHAD method.
