中文摘要：分别介绍了渗碳、淬火和回火热处理工艺模拟的数学模型，并在此基础上通过碳浓度、温度、组织和应力应变结果等的传递，以及对后续热处理模拟参数的必要修正，结合有限元原理实现了对渗碳-淬火-回火全工艺流程的数值模拟，为这种连续热处理工艺的设计与分析提供了新方法。
英文摘要：The numerical models for carburization quenching and tempering were introduced. Then based on these models, a new numerical simulation method about carburization quenching and tempering continuous process has been reported by transferring the results of carbon content, temperature, phase proportion, stress - strain, et al. And the necessary parameters which are in following process simulation as the initial condition were modified. A new useful method to design and analysis continuous heat treatment process was provided.
