Modeling of Spontaneous Para-equilibrium to Ortho-equilibrium Transition in Cementite Precipitation During Martensite Tempering
摘要
A model has been developed to simulate the precipitation kinetics of cementite during the tempering of martensitic steels, with a particular focus on the spontaneous transition of the solute partitioning behavior at the cementite/martensite growth interface from initial para-equilibrium (PE) to ortho-equilibrium (OE) conditions. The effect of this transition on the growth kinetics has been discussed and compared with experimental data.
