摘要
The isothermal section of the Ag-Cu-Ce ternary phase diagram at 500℃ containing 0～34 at% Ce have been determined by X-ray diffraction analysis and optical microscopy.It was found that Cu_2Ce-Ag_2Ce pseudo-binary system is characterized by having complete solid solubility at 500℃ and that the solid solubility of silver in Cu_5Ce is up to 41 at% at 500℃.The section consists of eight single phase re- gions,thirteen bi-phase regions and six tri-phase regions.
