Phase Equilibria in the Four-Component Cr-Ni-Re-Ta System at 1375 K

摘要

The phase equilibria in the four-component Cr-Ni-Re-Ta system at 1375 K are determined by a set of methods of physicochemical analysis using the graph method. It is experimentally found that the system exhibits nine four-phase equilibria, including α + β_(Cr) + β_(Ta) + λ, α + β_(Cr) + β_(Ta)+ a, α + β_(Cr) + γ + σ, α + β_(Ta) + λ+ μ, α + β_(Ta) + σ + x, α + γ + σ + (Re), α + λ +μ + Ni_2Ta, α + σ + x + (Re), and β_(Ta) + λ+ μ + NiTa_2.
