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。
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.
