(a) Stirling silver is an alloy of silver with 7.5 percent of copper. Describe the structure that one should expect if a specimen of stirling silver were to be heated from room temperature to 782°C, and allowed to come to equilibrium at this latter temperature.
(b) If the specimen of stirling silver, equilibrated at 782°C, is now slowly cooled to 400°C, what would be the nature of the microstructure? Give the amount and composition of each phase. (c) Finally, assume the specimen is cooled very rapidly (quenched) from 782°C to 400°C. Describe the structure that one might expect.
