The 450 °C isothermal section of the Zn-Fe-Al-Sb quaternary system with Zn fixed at 93 at.% has been studied experimentally using x-ray diffraction and scanning electron microscopy coupled with energy dispersive spectroscopy. The (L + AlSb) field is in equilibrium with other phase fields in the section, except those near the 93Zn7Fe corner. The solubility of Sb in ζ, δ, T, Fe 2 Al 5 , and FeAl 3 phases is very limited. The Zn-Fe-Al ternary phase T (Al 6 Fe 8 Zn 86 ) was found to be in equilibrium with L, δ, Fe 2 Al 5 , and AlSb phase. The maximum solubilities of Zn in AlSb, Fe 2 Al 5 , and FeAl 3 are 5.3, 12.3, and 6.2 at.% respectively. Zn can be dissolved in all compounds existing in the equilibrium alloys. Five four-phase regions and four three-phase regions have been confirmed experimentally.
