Abstract: | 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, ErFe12?xAlx with 5 ≤ x ≤ 8 (ThMn12-type), ErFe1+xAl1?x with ?0.2 ≤ x ≤ 0.75 (MgZn2-type), ErFe3?xAlx with 0.5 < x ≤ 1 (DyFe2Al-type), Er2Fe17?xAlx with 4.74 ≤ x ≤ 5.7 (TbCu7-type) and Er2Fe17?xAlx with 5.7 < x ≤ 9.5 (Th2Zn17-type), seven extensions of binaries into the ternary system; ErFexAl3?x with x < 0.5 (Au3Cu-type), ErFexAl2?x with x ≤ 0.68 (MgCu2-type), Er2FexAl1?x with x ≤ 0.25 (Co2Si-type), ErFe2?xAlx with x ≤ 0.5 (MgCu2-type), ErFe3?xAlx with x ≤ 0.5 (Be3Nb-type), Er6Fe23?xAlx with x ≤ 8 (Th6Mn23-type), and Er2Fe17?xAlx with x ≤ 4.75 (Th2Ni17-type) and one intermetallic compound; the ErFe2Al10 (YbFe2Al10-type). |
