The aim of this work is to study the anisothermal decomposition of austenite at two different austenisation conditions in a medium carbon microalloyed steel. In this sense, continuous cooling transformation diagrams (CCT) have been obtained for both austenisation conditions to determine the continuous cooling that allows the formation of a microstructure mainly formed of acicular ferrite with the best mechanical properties. The knowledge of the anisothermal decomposition of austenite in this steel has allowed to propose continuous cooling cycles for industrial application. That produce high volume fraction of acicular ferrite.Peer Reviewe
