Johnson– Mehl–Avrami equations were found for three austenitizing conditions and a direct relation between the time exponent and the transformation time was revealed.en-USNb microalloyed steelsFerritic grain growth kineticsAustenitizingEffect of the austenitizing temperature on the kinetics of ferritic grain growth under continuous cooling of a Nb microalloyed steel.Artigo publicado em periodicoO Periódico Scripta Materialia concede permissão para depósito do artigo no Repositório Institucional da UFOP.
