Summary: | Physico-chemical analysis techniques, including X-ray diffraction and Scanning Electron Microscope–Energy Dispersive X-ray Spectroscopy, were employed to construct the isothermal section of the Er–Fe–Al system at 800
°C. At this temperature, the phase diagram is characterized by the formation of five intermediate phases, ErFe
