Microstructure Modelling for Phase Transformation in Low Carbon Steel

The microstructures of phase transformation by using quntitative metallogra phy was studied. On the basis of analyzing the effects on the microstructures of phase transformation the model of transformation kinetics X=1-exp(-0.642t^0.086), and the model of ferrite grain size D_α=5.7×D_γ^0.46×C_r^-0.26 are constructed and obtained.
