摘      要：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 ＋ *** ternary compound is observed in the two isothermal *** isothermal sections are contrasted with the previous study.
