Abstract

The isothermal section at 650°C and the vertical section Fe-(Ga0.75Al0.25) of the Fe-rich portion in the Fe – Ga – Al ternary system were determined using optical microscopy, scanning electron microscopy, energy dispersion X-ray spectroscopy, X-ray diffraction and differential thermal analysis. The isothermal section of the Fe-rich portion consists of 4 single-phase regions: A2, B2, D03, D019, and 4 two-phase regions: A2 + B2, A2 + D03, D03 + D019 and B2 + D019. No fcc L12 phase region occurs in the isothermal section of the Fe-rich portion. The vertical section Fe-(Ga0.75Al0.25) of the Fe-rich portion consists of 3 single-phase regions: A2, B2 and D03, 4 two-phase regions: A2 + D03, D03 + D019, A2 + L12 and D03 + L12, and 2 three-phase regions: D03 + D019 + L12 and A2 + D03 + L12.

Keywords: Iron – gallium – aluminum system; Phase diagram; Isothermal section; Vertical section
