Effect of the austenitizing temperature on the kinetics of ferritic grain growth under continuous cooling of a Nb microalloyed steel.

Resumo
The continuous cooling kinetics of the nucleation and growth of the ferritic phase was studied on a Nb microalloyed steel. Johnson– Mehl–Avrami equations were found for three austenitizing conditions and a direct relation between the time exponent and the transformation time was revealed.
