The 680 °C and 800 °C isothermal sections of the Fe-Al-Sb system

The 680 °C and 800 °C isothermal sections of Fe-Al-Sb ternary system have been determined experimentally by means of optical microscopy, scanning electron microscopy coupled with energy-dispersive spectrometry and X-ray diffraction. No ternary compound has been found in this system at 680 °C and 800 °C. Seven three-phase regions have been confirmed in the Fe-Al-Sb ternary system at 680 °C and six three-phase regions exist in the 800 °C isothermal section.
