Fine Grained Ferrite by Continuous Recrystallization of Cold-Rolled Martensite

Continuous recrystallization process was suggested as the main mechanism responsible for the evolution of microstructure during tempering of cold-rolled martensite, where a fine-grained ferritic structure with dispersed carbides was achieved. In this mechanism, the collapse of lamellar structure due to surface tension, spheroidization caused by boundary tensions, and further spheroidization and growth can be identified. It was also shown that it is possible to control the mechanical properties of low-carbon steel sheets by this simple thermomechanical process
