Effect of Prior Recovery on the Recrystallization of Carbon Steel

Abstract

An investigation has been carried out, using optical metallography and hardness measurement methods, to ascertain the effect of prior-recovery heat-treatment on the rate of recrystallization in mild steel. The results reveal a definite correlation between the combined effect of cold-work and degree of recovery on the one hand, and recrystallization tendencies of mild steel on the other hand. Specimens with long-time prior-recovery treatment (up to 120 minutes) show longer recrystallization times than those without pre-recovery, annealing.

It is felt that as a result of prior-recovery, there is a remarkable reduction in recrystallization driving forces, and this ultimately leads to a change of the recrystallization process from the usual "discontinuous" to the characteristically sluggish "continuous" mechanism.
