The phase diagram of the Cu–In–Sb ternary system is of importance in predicting the
interface reaction between In-based solder materials and the Cu substrate. The liquidus
surface, invariant equilibria and four vertical sections of the Cu–In–Sb ternary system were
calculated by the CALPHAD method using binary thermodynamic parameters included in
the COST531 database. Alloys, representing two isopleths from indium corner with molar
ratio of copper and antimony equal to 1/3 and 1/1 and two isopleths from antimony corner …

Phase diagram of the Ge–In–Sb ternary system was investigated using differential thermal
analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry
(EDS), and X-ray powder diffraction (XRD) methods. Experimentally obtained results were
compared with the results of thermodynamic calculation of phase equilibria using calculation
of phase diagram (CALPHAD) method and literature data. Phase transition temperatures of
alloys with overall compositions along three selected vertical sections Ge–In 0.5 Sb 0.5, In …
