摘　　要：通过将渗碳模拟结果作为后续淬火模拟的初始条件,并根据碳浓度变化修正淬火模拟的材料参数,可实现渗碳-淬火连续热处理过程的数值模拟。研究中采用这种方法模拟了端淬试样的渗碳-淬火连续热处理过程,并据此分析了渗碳过程对后续淬火过程的影响。Carburization-quenching continuous heat treatment process was simulated by taking the carburization simulation results as the initial condition of the follow-up quenching simulation, modifying the material parameters according to the updated carbon content as well. The carburization-quenching continuous process of a jominy specimen was simulated by this method, and then the effect of carburization on follow-up quenching process was discussed.
