Chapter 13.12, Problem 14E

For the copper (1) + silver (2) system, identify the type and number of stable phases at equilibrium and their composition.

1. a. 30 wt% copper and 1000°C
2. b. 70 wt% copper and 600°C
3. c. 70 wt% copper and 825°C

Figure 13-15 The solid–liquid equilibrium for the copper + silver system. The eutectic composition is 28.1% by weight copper.
