The isothermal section at 800 °C and an AlSb–Zn quasi-binary cut in the Al–Sb–Zn system

The Al–Sb–Zn ternary phase diagram was calculated from thermodynamic Gibbs energies using the CALPHAD method and experimentally investigated using differential thermal analysis (DTA), differential scanning calorimetry (DSC) and a Calvet-type micro-calorimeter. An SSOL4 thermodynamic database was used for the thermodynamic predictions. A scanning electron microscope (SEM) equipped with an energy-dispersive spectrometer (EDS) and X-ray powder diffraction (XRD) analyses were used to confirm the predicted phase diagram. Good agreement was found between the experimental results and the predictions.
