why will the mechanical strength of an over-aged aluminum alloy decrease?

Question

In over-aging of the aluminum alloy, the size of the individual particle increases, but the number of particles decreases. This causes few obstacles to the movement of dislocations, therefore, the mechanical properties decreases, so the mechanical strength will also decrease.
