1. You are given an equilibrium-solidified Al-Cu alloy indicated in Figure 1. Please advise a heat treatment procedure that can be used to achieve a maximum strength without losing a significant amount of ductility. Please draw your temperature history in the temperature-time coordinate beside the phase diagram and describe the microstructure change in each heat treatment step.
