Abstract

Abstract: Phase relations in Zr-Ni-Sc ternary system were investigated experimentally through alloy sampling approach. Isothermal sections at 973, 1173, and 1273 K were constructed from the results of electron probe microanalysis (EPMA) and X-ray diffraction (XRD). No ternary phase has been detected in all these sections. Combining experiment and reasonable speculation, 12, 15 and 13 three-phase zones were obtained at 973, 1173 and 1273 K, respectively. Liquid region with a large composition range at 1273 K was found although its real boundary was estimated. The intermetallic compounds, Ni2 Sc, NiSc and NiSc2, exhibit remarkable ternary solubility of Zr along the isoconcentration of Ni. Highlights: Isothermal sections in the Zr-Ni-Sc ternary systems at 973 K, 1173 K and 1273 K. At 1273 K, Liquid with a large composition range occurs. The compounds Ni2 Sc, NiSc and NiSc2 exhibit remarkable ternary solubility of Zr.
