(c) Figure 24 (c) shows the phase diagram for Ag-Cu binary system. At 780 C+AT, make a phase analysis for Ag-Cu alloy (50 wt% Cu) in its composition by assuming the system in equilibrium condition. i. What phases are present? ii. What is the chemical composition of each phase? iii. What amount of each phase is present (the portion of each phase)? iv. Sketch the microstructure at 550 C.
