The hardening case depth and hardnesscurve can be changed by adjusting heating time, heating power and cooling speed during induction hardening.
在感应淬火中，通过改变加热时间、加热功率和冷却速度可以改变淬硬层深度和硬度梯度。

According to the tempering temperature and hardnesscurve, the redistribution of residual stress is associated with the transformation of residual austenite.
由回火温度与硬度变化曲线证实，残余应力重新分布是与残余奥氏体转变相关联。
