Strengthening of Alloys

Strengthening of the alloys is required as metals become weak due to various lattice defects, metal bonding phenomena. The strength of the metals is not enough for any mechanical work. The internal dislocations of any metals arise due to forming processes. Due to the movement of these dislocations, the metals are plastically deformed.

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.
