Concept Check 9.3 Is it possible to have a copper-nickel alloy that, at equilibrium, consists of an a phase of composition 37 wt% Ni-63 wt% Cu, and also a liquid phase of composi- tion 20 wt% Ni-80 wt% Cu? If so, what will be the approximate temperature of the alloy? If this is not possible, explain why. [The answer may be found at www.wiley.com/college/callister (Student Companion Site).]
