| Abstract: | The phase diagram of the Dy–Ga binary system was reinvestigated by differential scanning calorimetry (DSC) and X-ray diffraction (XRD) analysis. The existence of the compounds Dy5Ga3, DyGa, DyGa2, DyGa3 and DyGa6 was confirmed at low temperature in this system. A new high temperature intermetallic compound may exist between DyGa and DyGa2 at a temperature range between 1217 and 1295 °C. No polymorphic transition was found for DyGa3. The phase diagram of the Dy–Ga binary system was constructed and modified. |
