Enhancing strength without sacrificing ductility in medium-carbon multiphase bainitic steel through increased intercritical annealing temperatures

Journal of Materials Research and Technology
In bainitic steels, enhancing strength often comes at the expense of ductility. In this paper, a medium-carbon multiphase bainitic steel was produced through intercritical annealing (IA) at various temperatures, followed by isothermal bainite ...
