Abstract

Analytical Models based on the classic development of Johnson-Mehl, Avrami and Kolmogorov (JMAK) has been used to model the recrystallization phenomenon for many years. More recently, computer simulation has been used to simulate microstructural evolution. In this work, the cellular automata method in 3D is used to develop a computer code to simulate recrystallization kinetics. Analytical theories are compared with cellular automata simulations and a good agreement is observed. Additionally, the effect of the distribution of the nuclei on the kinetics and on the microstructural path is evaluated. In this work, the methodology was applied having in mind the recrystallization phenomena. However, the computer program developed in 3D, based in the method of the cellular automata, is general and can be adapted to simulate nucleation and growth phase transformations.
