Introduction

The first data on the Ag-Bi-Cu system were reported by [1951Ava], who considered microstructure of alloys near the binary Ag-Cu eutectic depending on the cooling rate. [1976Zan] reported results of rapid quench-cooling experiments in the Ag rich part of the system. A eutectic reaction was found to exist at 240 ± 5°C, but the phases in equilibrium were not specified. This work was reviewed by [1980Hen] and [1988Hen]. [1988Liu, 1989Liu] investigated the entire ternary system in 12 vertical sections by thermoanalysis (DTA) in an atmosphere of dry nitrogen. They found that the ternary Ag-Bi-Cu system is a simple eutectic one with the invariant reaction at 258°C. [1998Shu] has calculated the liquidus surface using a model of ideal solution of self-associates and compared the result with that measured by [1989Liu]. [2004Doi...
