Reinvestigation of the Phase Diagram of the Dy-Ga Binary System

摘要：

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