A COMPREHENSIVE MODEL OF RECRYSTALLIZATION FOR INTERSTITIAL-FREE STEEL

A computer model of the recrystallization process is proposed which in corporates both microstructure and crystallographic texture using a th ree dimensional lattice. This model is applied to the recrystallizatio n of cold-rolled interstitial free (IF) steel, assuming oriented nucle ation al the grain boundaries. The nucleation mechanism is implemented using the concept of subgrain coalescence. This model provides the qu antitative information of a change in the volume fraction of the recry stallization, the grain size distribution, and the crystallographic te xture.
