Abstract
The phase relations of the Zn-Al-Co-Sb quaternary system at 450 and 600 °C with Zn fixed at 93 at.% have been determined experimentally by means of scanning electron microscopy coupled with energy dispersive x-ray spectroscopy and x-ray diffraction. Four four-phase regions and three four-phase regions have been confirmed in these isothermal sections at 450 and 600 °C, respectively. The maximum solubilities of Zn in AlCo, Al5Co2 and Al13Co4 are 4.89, 18.98 and 7.85 at.%, respectively. Furthermore, no new ternary and quaternary compounds have been detected in this study.
