The room temperature section of Cu-Dy(≤35wt-%)-Ni 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_2N_(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 seetion.No any new phase was ob- servered.The solubility of Dy in α-phase is up to 2 wt-%.

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。
