采用X射线衍射和金相显微分析方法研究了Ag-Cu-Ce三元系中含0～34at％Ce的区域,测定了500℃的等温截面。发现Cu_2Ce和Ag_2Ce间形成连续固溶体;Ag在Cu_5Ce中有高达41 at％的固溶度。在该截面上存在8个单相区、13个二相区和6个三相区。
The area containing 0 ~ 34at% Ce in Ag-Cu-Ce ternary system was investigated by X-ray diffraction and metallographic analysis. The isothermal section at 500 ℃ was measured. It was found that Cu_2Ce and Ag_2Ce formed a continuous solid solution; Ag in Cu_5Ce up to 41%% of the solid solubility. There are 8 single-phase zones, 13 two-phase zones and 6 three-phase zones in this section.
