Given a binary phase diagram of Cu-Ag. the composition of an alloy is 85% Cu, and the temperature is 800 C; and assuming that the alloy is at equilibrium, determine the following: 1) what phase(s) is (are) present 2) the composition(s) of the phase(s) 3) the mass fraction(s) of the phase(s) 4) write the eutectic reaction for cooling.
