Abstract
Abstract
The complete isothermal sections of the Hf–Nb–Ni system at 950 and 1100 °C were constructed, in which the phase constituents and compositions of alloy samples were determined by scanning electron microscopy with energy dispersive X-ray spectroscopy, and X-ray diffraction. Nine three-phase regions at 950 °C and nine three-phase regions at 1100 °C were confirmed. Four three-phase regions at 950 °C and five three-phase regions at 1100 °C were proposed. The solid solubilities of third components in the binary compounds were determined. A new ternary compound τ with Hf2Rh structure was found.
