摘　　要：采用三元扩散偶技术测定了Ni-Mo-Re三元系1473K的等温截面,借助电子探针微区成分分析方法分析了Ni-Mo-Re三元扩散偶的相区成分,并对其相关系进行了研究。Ni-Mo-Re三元扩散偶在1473K时存在3个二元中间化合物:χ,σ和NiMo,在此温度的扩散偶中未发现三元中间化合物。经分析,Ni-Mo-Re三元系在1473K存在4个三相区:Re+Ni+χ;Ni+NiMo+σ;σ+χ+Ni;σ+Mo+NiMo。The isothermal section and the components of the phase regions for Ni-Mo-Re ternary system at 1473 K was determined by means of diffusion triple and electron microprobe analysis. The results indicate that there existed three binary intermediate compounds： χ, σ and NiMo. In this diffusion triple, no ternary compound was observed. There were four three-phase regions found at this temperature：Re＋Ni＋χ;Ni＋NiMo＋σ;σ＋χ＋Mo＋NiMo.
