The mechanical properties such as hardness and ultimate tensile strength of metals depend on the
grain size, which have to be properly controlled and optimized to ensure the better economy and
desirable mechanical characteristics of the metals. In order to study the microstructure evolution
of AA1070, many experimental tests were conducted at different cold working and annealing conditions.
Utilizing the experimental results, the static recrystallization and grain growth behavior
of AA1070 have been investigated and the developed equations that can be used to the FEM of the
annealing process have been obtained. The agreement between numerical modeling and experimental
results is reasonably good for this material. The results showed that the recrystallization
and grain growth behavior of AA1070 was evidently affected by both the annealing temperature
and plastic strain.
