The isothermal sections of the Co-Nb-Ni ternary system at 1373 K and the Ni-Mo-Re ternary system at 1473 K were determined by means of diffusion triple and electron probe microanalysis(EPMA).The results indicate that there are three three-phase regions found in the Co-Nb-Ni ternary system at 1373 K:(Ni,Co) + NbCo3 + Ni3Nb,NbCo3 + NbCo2 + Ni3Nb,and NbCo2 + μ + Ni3Nb;and four three-phase regions found in the Ni-Mo-Re ternary system at 1473 K:Re + Ni + χ,Ni + NiMo + σ,σ + χ + Ni,and σ + Mo + NiMo.No ternary compound is observed in the two isothermal sections.The isothermal sections are contrasted with the previous study.
The isothermal sections of the Co-Nb-Ni ternary system at 1373 K and the Ni-Mo-Re ternary system at 1473 K were determined by means of diffusion triple and electron probe microanalysis (EPMA). The results indicate that there are three three -phase regions found in the Co-Nb-Ni ternary system at 1373 K: (Ni, Co) + NbCo3 + Ni3Nb, NbCo3 + NbCo2 + Ni3Nb, and NbCo2 + μ + Ni3Nb; and four three-phase regions found in the Ni Ni-Co-Ni ternary system at 1473 K: Re + Ni + χ, Ni + NiMo + σ, σ + χ + Ni, and σ + Mo + NiMo.No ternary compound is observed in the two isothermal sections. contrasted with the previous study.
