摘　　要：本文用X射线衍射法对Cu-Dy-Ni(Dy≤35wt-％)三元合金系相图的室温截面作了测定。结果如下:它有4个单相区(α,Dy_2Ni_(17),DyNi_5和DyCu_5);5个两相区(α+Dy_2Ni_(17),Dy_2Ni_(17)+DyNi_5,DyCu_5+DyNi_5,α+DyNi_5和DyCu_5+α);和两个三相区(α+Dy_2Ni_(17)+DyNi_5和α+DyNi_5+DyCu_5)。没有发现新相。Dy在α相中的最大固溶度约为2wt-％Dy。The room temperature section of Cu-Dy (≤35wt-%)-Ni ternary phase diagram has been determined by means of X-ray diffraction technique. The results are as follows: four single-phase regions (α, Dy_2Ni_(17), DyNi_5 and DyCu_5), five two- phase regions (α+Dy_2Ni_(17), Dy_2Ni_(17) + DyNi_5, DyCu_5 + DyNi_5, α+DyNi_5 and DyCu_5+α) and two three-phase regions (α+ Dy_2Ni_(17) + DyNi_5 and α+ DyNi_5 + DyCu_5) exist in the diagram. NO any new phase has been observed. The solubility of Dy in α-phase is up to 2wt-%.
