Flash Processing (FP) of steels involves rapid heating and cooling. This process has been shown to be a viable means of producing high strength by producing a mixed microstructure of bainite and martensite, while maintaining acceptable formability. Previous research on Flash Processing focused on spheroidized chromium containing steels grades, including 41XX and 86XX. While the above microstructure evolution was rationalized based on incomplete dissolution of carbides in the austenite matrix, the extension of the same mechanism to low carbon steels is not established. Current research focuses on microstructure evolution during flash processing of 10XX series steel through Gleeble thermo-mechanical simulation samples and computational thermodynamic/kinetics simulations. Preliminary results from flash processed steels exhibit through thickness variations of hardness resulting from the response of these steels to imposed temperature gradients and cooling conditions. Standardization of the flash processing through definition of initial microstructure will be discussed.
