Chapter 9: Phase Diagrams
Chapter 9 -1 ISSUES TO When we combine two equilibrium state do we get? In particular, if we composition ( , wt% Cu - wt% Ni), and--a temperature (T) many phases do we get?What is the composition of each Phase ?How much of each Phase do we get?

• Phases : The physically and chemically distinct material regions that result (e.g., α and β). Aluminum-Copper Alloy Components and Phases α (darker phase) β (lighter phase) Adapted from chapter-opening photograph, Chapter 9, Callister 3e. A phase maybe defined as a homogeneous portion of a system that has
