The Ni-Re-V (Nickel-Rhenium-Vanadium) System

The (nickel-rhenium-vanadium (Ni-Re-V) system was investigated to demonstrate the presence of a single isothermal section some and other aspects. The Ni-Re system was a simple peritectic system where the peritectic reaction L + ε ↔ γ occurred at 1620 °C and where ε and γ were the terminal solid solutions (Re) and (Ni). The Re-V system had two intermediate phases, such as σ and δ where the σ phase formed a pertiectic reaction L + ε ↔ σ at 2460 °C. The δ phase formed through a peritectoid reaction σ + α ↔ δ at 2280 °C. Investigations also revealed that the binary systems Ni-Re, Ni-V, and Re-V systems had seven intermediate phases, while the Ni-Re-V ternary system had one intermediate phase σ'.
