In contrast,recrystallization involves the formation of new strain-free grains in certain parts and the subsequent growth to consume the deformed or recovered microstructure. Recrystallization of the deformed microstructure is often called primary recrystallization;abnormal grain growth which may occur in fully recrystallized material is called secondary recrystallization. Divide primary recrystallization into two regimes:nucleation(the first appearance of new grains)and growth(the new grains replace deformed material).
