The stable phase for Al and Zn at room temperature is fcc and hcp, respectively.
1. Label all the phase regions in the phase diagram
2. Label all invariant points on the attached phase diagram
3. draw the Gibbs Free Energy versus composition diagram and activity diagram for each phase at:
a. 600C
b. 650C
