(a) The copper-silver phase diagram is shown in Figure 5. Figure 5: A phase diagram for elements A and B. (i) Sketch a typical eutectic phase diagram with components A and B as shown in Figure 5 on your answer book. Copper has a higher melting point than silver. Refer to the silver-rich solid phase as gamma () and the copper-rich solid phase as delta (). Denote the liquid as L. (ii) Determine the phases that are present and the composition for each phase in Cu-85 wt%Ag at 800C
