tempering curve

Investigation on microstructural feature and tempering curve of low carbon martensite after cryogenic treatment

深冷处理后低碳马氏体的形态和回火特性研究

According to the tempering temperature and hardness curve, 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。

Fe_3C was transformed into Fe_3 ( C, B) during a rather long-term tempering. The kinetic curve of Fe_3 ( C, B) is the ε shape,, its nose temperatures are 700 ℃ and 550 ℃, respectively.

Fe3（C，B）则在较长时间回火时由Fe3C转变而成，其形成的动力学曲线是以700℃和550℃为鼻尖的ε形。

Its CCT curve was determined by test. The influence of quenching and tempering temperature on the mechanical properties was also studied.

试验测定了该钢的CCT曲线，探讨了淬火和回火加热温度对该钢力学性能的影响。

The tempering curve of remaining thermal quenching is higher than that of two times quenching.

余热淬火的回火曲线高于二次淬火的回火曲线；
