Model of Primary Recrystallization in Pure Copper

A new model that describes primary recrystallization in metals has been proposed. This model determines the rate of recrystallization nucleus growth in terms of the kinetics of the decreasing power of disclination dipoles distributed within nucleus boundaries. The equation relating the volume fraction of recrystallized material to the temperature and annealing time has been derived. This equation has the form of the Avrami equation at n = 1 and an activation energy of diffusion along nonequilibrium grain boundaries.
