The 650 and 750 °C isothermal sections of the Cr-Sb-Fe ternary system were determined by means of scanning electron microscopy, energy dispersive spectroscopy and x-ray diffraction. More than 40 alloys were prepared by a powder metallurgy method. Two continuous solid solution phases (Fe, Cr)Sb and (Fe, Cr)Sb2 were clearly identified. Two three-phase regions have been confirmed in the Cr-Sb-Fe ternary system at 650 and 750 °C isothermal sections. No ternary compound was found in this system.
