3) You see Al-Cu phase diagram below and two microstructures (A and B) having the same nominal composition of 3 percent Cu. In these microstructures, matrix is a and spheres refer to CuAl₂ particles. In A and B, the size of big particles are the same. a) For the same volume constant, if we heat treat the both microstructures at T₁ for a long time, is there any changes in both microstructures? If so, what is that? And is the changes the same for both A and B? Is the rate of changes the same for A and B? Draw the final microstructures of A and B if any changes occur you think so.
