Title
Development of Recrystallization Texture during Continuous Annealing in Extra Low Carbon Al Killed Steels
박용범Yong Bum Park, 한봉희Bong Hee Hahn
Abstract
The ecrystallization behaviors during continuous annealing process were studied in extra low carbon Al-killed steels with varying Mn content. The less the Mn content, the higher the nucleation rate of {111} grains. The {111} recrystallization it difficult when Mn content is excessively high. There exists, an optimum range of Mn content, annealing temperature and annealing time. Cold rolled texture is {111} $lt;hkl$gt; fibre texture and recrystallization texture is mainly of {111} $lt;112$gt; component. A model for nucleation and grain growth is proposed to explain the recrystallization process from {111} $lt;hkl$gt; cold rolled texture to {111} $lt;112$gt; recrystallized texture with movement of coincidence boundary.
