Abstract

The Ni-Pr phase diagram on the Pr-rich side was revised using differential thermal analysis, differential scanning calorimetry, and scanning electron microscopy. The existence of four stoichiometric compounds, Ni2Pr, NiPr, Ni3Pr7, and NiPr3, was confirmed; however, the melting temperatures of 766 °C (NiPr), 566 °C (Ni3Pr7), and 562 °C (NiPr3) are considerably different from the previously reported values. The same was true for the four eutectic reactions, which were determined to be as follows: liquid (L) (45±1 at.% Pr) ↔ Ni2Pr+NiPr at a mean temperature of 732±5 °C; L (65±1 at.% Pr) ↔ NiPr+Ni3Pr7 at a mean temperature of 550±2 °C; L (72±2 at.% Pr) ↔ Ni3Pr7+NiPr3 at a mean temperature of 557±2 °C; and L (77±1 at.% Pr) ↔ NiPr3+Pr.
