Microstructures of AISI1050 disk after quenching process (cooling from 880 degrees C to 150 degrees C by 6% AQ251 quenchant) were simulated by DEFORM-HT software, and the corresponding mechanical properties were calculated by the finite difference method (FDM). Above all, thermo-physical parameters and diagrams of CCT curve were calculated by JMATPRO software, and then the characterization of phase transformation and CCT curve were fatherly analyzed. Besides, the simulation of multi-phase microstructure considering initial thermo-physical parameters was realized by DEFORM-HT. The FDM method helps to obtain the volume fraction of single phase, and a weight function considering carbon equivalent of phases was introduced to predict the final hardness of multi-phase and quenched microstructure according to the single phase hardness simulated. This helps to explain the relationship between final hardness and various single phases.
