(a) A copper?75 percent silver alloy is slowly cooled from the liquid state to 900°C, and allowed to come to equilibrium. Estimate the amount and composition of both the liquid and solid phases.
(b) Make a sketch of the 900°C equilibrium structure of the alloy.
(c) Now assume the alloy is slowly cooled to just below the eutectic temperature. What are the weight percentages and compositions of the phases and constituents at this point?
