The partial phase diagram of Ag-Cu-Tb system on the Ag-Cu-rich region at room temperature is investigated by X-ray diffraction and optical microscopy analyses. The section consists of six singlephase regions, nine binary phase regions and four ternary phase regions. No ternary intermetallic compound is found.
