The diagram of Ag-Cu-Bi system was constructed from the investigation of 12 internal sec- tions by DTA heating as well as cooling curves in an atmosphere of dry N_2.The composi- tion of ternary eutectic point melting at 258℃ lies in Ag(5.0)-Cu(0.5)-Bi(94.5) at.-%.The liquiduses of Ag-Cu,Ag-Bi and Cu-Bi binaries were reinvestigated.
