| 摘 要： | 通过建立合适的三维有限元模型，研究了P20钢大型模具按3种工艺进行淬火时的温度组织变化。模拟结果表明，工艺a造成了模块内过大的温度梯度；工艺b通过多次空冷加水淬使工件内的温度梯度下降；而工艺c使已转变的马氏体和贝氏体产生自回火。温度的模拟结果与测量结果一致。

| Abstract: | Based on the three dimensional Finite Element Method (FEM),the temperature and microstructure variations of large scale P20 steel mould during quenching in 3 different processes were studied.The results show that significant temperature gradient exists during quenching in process a.The temperature gradient is less steep during quenching in process b by alternative water and air cooling.And the transformed martensite and bainite are self tempered by process c.The calculated temperature is in agreement with the measured one. |
