Question:

For a 52 wt% Zn–48 wt% Cu alloy, make schematic sketches of the microstructure that would be observed for conditions of very slow cooling at the following temperatures:  950°C (1740°F), 860°C (1580°F), 800°C (1470°F), and 600°C (1100°F).  Label all phases and indicate their approximate compositions.

 

I have provided the diagram below for reference.
