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. ： Key words carburization; quenching; tempering; numerical simulation 钢铁材料的热处理是一个十分复杂的过程，很 应力 应变等结果作为后续模拟的初始条件，并对有
