摘要：

Recent works about the development of carbide-free bainitic (CFB) steels use chemical compositions that require too long isothermal treatments for the bainitic transformation, making it difficult their manufacture under industrial continuous annealing processes. The present work reports an approach for designing CFB steels based on a computer simulation of phase transformations as a function of chemistry. The effect of chemistry and isothermal bainitic treatment (IBT) time on the microstructure and mechanical properties of CFB steels are also investigated. Results show that CFB steels of third generation, containing about 96% of bainite, can be obtained from short IBT times, opening the possibility to obtain these steels under the said conditions.
