Abstract An improved Jominy curve hardness model was built for carburizing-quenching process. In contrast to the other hardness model, it avoids the computational heterogeneity of phase transformation and has strong operability. Finally the model was applied to the carburized Jominy and gear specimens of 17CrNiMo6 steel. Namely, the corresponding experiment results were utilized to verify the simulation results. Hardness distribution between the measured and simulated results shows good agreement. Especially the simulation accuracy on the low Jominy distance and the hardened layer was better than that on other positions.

渗碳淬火Jominy曲线硬度模型

摘要 针对渗碳淬火过程建立了改进的Jominy曲线硬度模型。与其他硬度模型相比，它避免了相变的计算异质性，具有很强的可操作性。最后将该模型应用于17CrNiMo6 钢的渗碳Jominy 和齿轮试样。即，利用相应的实验结果来验证模拟结果。测量和模拟结果之间的硬度分布显示出良好的一致性。特别是低Jominy距离和硬化层的模拟精度优于其他位置。
