摘要
通过对低合金钢经5GPa压力处理前后在冷却过程中固体相变温度、相变时间和相变激活能的测试与计算,探讨了低合金钢经5 GPa压力处理后对其在冷却过程中固体相变动力学的影响。结果表明:5 GPa压力处理能提高低合金钢组织中奥氏体向珠光体的转变温度和转变激活能,缩短转变时间,有利于低合金钢在冷却过程中的固态相变。
The effects of 5 GPa pressure treatment on the solid state phase transformation kinetic parameters of low alloy steel in following cooling process were investigated, based on the measurement and calculation of its solid state phase transformation temperature, duration and activation energy. The results show that the transformation temperature and activation energy of austenite to pearlite in low alloy steel after 5 GPa pressure treatment can be increased as well as the phase transformation time can be also decreased, and which is helpful for the solid-state phase transformation in low alloy steel during cooling process.
