The isothermal section of the Dy–Fe–Ge ternary system at 773 K

The isothermal section of the phase diagram of the Dy–Fe–Ge ternary system at 773 K has been investigated mainly by X-ray powder diffraction (XRD), with the aid of differential thermal analysis (DTA) and optical microscopy (OM). Sixteen binary compounds have been confirmed. Five ternary compounds DyFe4Ge2, DyFe2Ge2, DyFe6Ge6, Dy117Fe52Ge112, and Dy5Fe2Ge10 have been confirmed in this system at 773 K.
