Abstract
Ag-Cu-Te is a significant material system, and experimental measurements have been conducted to determine its liquidus projection. Aside from the terminal solid solution phases and binary compounds, there exists a ternary compound known as AgCuTe. The ten primary solidification phases include (Ag), Ag
Te, Ag
Te, Ag
Te
, (Te), CuTe, Cu
Te
, Cu
Te, (Cu), and AgCuTe. A liquid miscibility gap with a very wide compositional range is observed. When the alloys are at temperatures higher than those of the binodal curves, they are entirely molten. Interesting spherical-shaped microstructures are observed when the alloys solidify passing through the liquid miscibility gap. Furthermore, it has been determined that there are nine invariant reactions, consisting of three Class I reactions (L ↔ α + β + γ) three Class II reactions (L + α ↔ β + γ), and three Class III reactions (L + α + β ↔ γ). The highest and lowest invariant reaction temperatures are determined to be 849.0 °C and 308.0 °C, respectively.
