感应淬火是一种广泛使用的表面处理技术，已得到广泛研究。相比之下，短加热时间≤1秒的感应回火尚未得到彻底研究，也没有通过实验或模拟进行研究。此外，快速回火对感应表面淬火后残余应力的影响仅进行了肤浅的研究。进行了感应淬火和回火实验，加热时间均≤1s。观察到残余应力状态发生显着变化，导致表层残余应力从压缩应力转变为拉伸应力。整个淬火回火过程的多物理有限元模型已经开发并验证。相关机械性能、硬度和残余应力与实验结果吻合良好。最近报道的回火过程中相变诱导塑性已被发现在回火过程中残余应力的产生中起着关键作用。模拟进一步表明，常规热处理在回火至规定的表面硬度后会产生更有利的残余应力状态。通过考虑奥氏体化过程中的回火过程，硬化模拟可以推广到不同的初始状态，并允许预测过渡区的硬度最小值。
Induction hardening is a widely used surface treatment technique that has extensively been investigated. In contrast, induction tempering with short heating times≤ 1 s has not been investigated thoroughly, nor by experiment neither by simulations. Also, the influence of rapid tempering on the residual stresses after induction surface hardening has only been investigated superficially. Induction quench and temper experiments were performed, both with heating times≤ 1 s. A significant change of the residual stress state was observed, leading to a shift from compressive to tensile residual stresses in the surface layer. A multiphysical FE-model for the whole quench-and-temper process has been developed and validated. A good agreement with the experiments for the relevant mechanical properties hardness and residual stress could be achieved. The recently reported transformation induced plasticity during tempering has been found to play a key role in the development of residual stresses during tempering. The simulations further indicate that conventional heat treatment leads to more favorable residual stress states after tempering to a prescribed surface hardness. By accounting for tempering processes during austenitization, the hardening simulation could be generalized to different initial states and allows for the prediction of hardness minima in the transition zone.
