Experimental Investigation and Thermodynamic Calculations of the Bi-Ge-Sb Phase Diagram
Abstract
A phase diagram of the Bi-Ge-Sb ternary system was investigated experimentally by differential thermal analysis (DTA), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), and X-ray powder diffraction (XRD) methods and theoretically by the CALPHAD method. The liquidus projection; invariant equilibria; and three vertical sections, Sb-Bi0.5Ge0.5, Ge-Bi0.5Sb0.5, and Bi-Ge0.5Sb0.5, as well as isothermal sections at 773 K and 373 K (500 A degrees C and 100 A degrees C), were predicted using optimized thermodynamic parameters for constitutive binary systems from the literature. In addition, phase transition temperatures of the selected samples with compositions along calculated isopleths were experimentally determined using DTA. Predicted isothermal sections at 773 K and 373 K (500 A degrees C and 100 A degrees C) were compared with the results of the SEM-EDS and XRD analysis from this work. In both cases, good agreement between the extrapolated phase diagram and... experimental results was obtained. Alloys from the three studied vertical sections were additionally analyzed using the Brinell hardness test.
