A MODEL FOR BAINITIC TRANSFORMATION KINETICS WITH PARABOLIC NUCLEATION RATE

1. IntroductionDue to the good toughness and high strength, bainitic steels are widely used in structural engineering such as supporting rollers, rail steels and high-pressure vessels. Manysteels are treated to obtain bainitic structure as more as possible. Relative heat treatmentprocessing parameters are determined convelltionally by try--and-error methods. The development of numerical simulation makes it possible to optimize heat treatment processingwith less cost and time. One of the impor…
