摘要: 以17Cr2Ni2Mo和20CrNi2Mo合金钢为例,在前人扩散系数计算模型D(T,C)的基础上添加合金因子Q,提出了一种新的扩散系数的计算模型D(T,C,Q),同时与另一扩散系数模型D(T,C,M)进行比较,利用DEFORM软件对两种合金钢的渗碳过程进行了模拟分析,再通过剥层试验对模拟结果进行验证。结果表明,考虑合金元素影响的D(T,C,Q)与D(T,C,M)模型要比D(T,C)模型模拟精度高。17Cr2Ni2Mo钢的D(T,C,Q)模型的模拟精度要高于D(T,C,M)模型,20CrNi2Mo钢的D(T,C,M)模型的模拟精度要稍高于D(T,C,Q)模型,说明D(T,C,Q)模型在计算扩散系数时具有较高的准确性。

Abstract: Taking alloy steels 17Cr2Ni2Mo and 20CrNi2Mo as examples, a new diffusion coefficient calculation model D(T,C,Q) was proposed by adding an alloy factor Q on the basis of previous diffusion coefficient calculation model D(T,C). By comparison with another diffusion coefficient calculation model D(T,C,M), the carburizing process of the two alloy steels was simulated and analyzed by using DEFORM software, and the simulation results were verified by stripping test. The results show that the simulation accuracy of D(T,C,Q) and D(T,C,M) models affected by alloy elements is higher than that of D(T,C) model. The simulation accuracy of D(T,C,Q) model of the 17Cr2Ni2Mo steel is higher than that of D(T,C,M), and that of D(T,C,M) model of the 20CrNi2Mo steel is slightly higher than that of D(T,C,Q) model, indicating that the D(T,C,Q) model has higher accuracy in calculating the diffusion coefficient.
