LIQUIDUS OF Ag-Cu-Bi SYSTEM

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.-%.Theliquiduses of Ag-Cu,Ag-Bi and Cu-Bi binaries were reinvestigated.
