N2 - The thermodynamic calculation of ternary phase diagrams was used to predict the type of topologically close-packed (TCP) phase in Mo-rich Ni based single crystal superalloys. The precipitation behavior of TCP phase in Mo-rich single crystal superalloys can be described by Ni-Mo-Re, Co-Mo-Re, Ni-Cr-Mo, Co-Cr-Mo, Ni-Cr-Re and Co-Cr-Re ternary systems, and NiMo, P, σ, μ and R phases tends to form in above ternary systems. Meanwhile, only NiMo phase exist in Ni-Mo-Al/Ta system, both Re and Cr additions promote the formation of P phase and σ phase, and Co addition is found to promote the formation of μ phase.
