In order to determine the existence of phases and relationships in the Er–Fe–Mn system at 773K, we have carried out this work mainly by X-ray powder diffraction with the aid of differential thermal analysis and have obtained the conclusions below. The existence of seven binary compounds ErFe2, ErFe3, Er6Fe23, Er2Fe17, ErMn12, Er6Mn23, ErMn2and one intermediate solid solution γ(Fe·Mn) have been confirmed in this system. Er6Fe23and Er6Mn23form continuous solid solution Er6(Fe23−XMnX) (0≤X≤23). At 773K, the maximum solid solubility of Fe in αMn, ErMn12, ErMn2phases and Mn in ErFe2, Er2Fe17, αFe phases are about 31, 69, 13at% Fe and 47, 28, 8at% Mn, respectively. The homogeneity range of γ(Fe·Mn) phase extended from about 34at% Mn to 52at% Mn. The maximum solid solubility of Er in γ(Fe·Mn) phase is about 2at% Er. The isothermal section consists of ten single-phase regions, sixteen two-phase regions and seven three-phase regions. No ternary compounds were observed at 773K in this system.
