建立了单频和双频感应淬火的二维计算模型。工艺的具体方面，如非线性磁性材料的行为和相变动力学的淬火和回火AISI 4140被认为是。感应表面淬火实验已进行验证的目的。测量方法用于提取输入数据，如磁性材料的行为，电流，和有效的加热时间。将冶金特征和硬度分布与模拟获得的结果进行比较。温度历史、硬度深度剖面和硬度分布具有良好的一致性。
A 2D computational model of single and simultaneous dual frequency induction hardening has been developed. Process specific aspects such as the nonlinear magnetic material behavior and phase transformation kinetics of quenched and tempered AISI 4140 are considered. Induction surface hardening experiments have been conducted for validation purposes. The measuring methodologies used to extract input data such as the magnetic material behavior, the current, and the effective heating time are presented. Metallurgical characterization and hardness profiles are compared with the results obtained from simulations. The temperature history, hardness depth profile, and hardness distribution are in good agreement.
