The Austenite Decomposition Kinetics Based on CCT Curves and its Application in 22MnB5 Steel
This work mainly focuses on establishing the corresponding relationship between isothermal and non-isothermal transformation data.The additivity hypothesis is adopted to describe the incubation of diffusional phase transformation, and a mathematical reverse method is presented to obtain a computational isothermal transformation curve from an experimental continuous cooling transformation (CCT) curve.Furthermore, a general calculation method of incubation process is presented to simulate the incubation process when the cooling rate is not constant, using only data from the CCT curve.Finally, the experimental CCT of boron steel (22MnB5) is adopted to obtain the calculated TTT curves using the established mathematical model, the reverse TTT curves can be also used to simulate the complex heat treatment process.
