Janet, The areas on the right and left of that diagram represent the single phase solid areas in the Ag Cu system. What that means is at the ratios and temperatures shown the alloy formed is a single phase solid solution. The reading of phase diagrams is a fairly complex subject and is not one to be condensed to a single email response The illustration below is the Cu-Zn phase diagram (Figure 10.19). A vertical line at a composition of 64 wt% Zn-36 wt% Cu has been drawn, and, in addition, horizontal arrows at the four temperatures called for in the problem statement (i.e., 900°C, 820°C, 750°C, and 600°C).

(c) The Ag-Cu phase diagram (Figure 9.7) is shown below; the point labeled “C” represents the 55 wt% Ag-45 wt% Cu composition at 900°C. As may be noted, point C lies within the Liquid phase field. The ternary alloy system Ag-Cu-Si was investigated in detail for the first time. The phase diagram was analysed by means of light optical microscopy, powder x-ray diffraction, differential thermal analysis (DTA) and scanning electron microscopy in combination with energy dispersive x-ray spectroscopy. The complete isothermal section at 650 °C was studied experimentally, and several additional ...
