| 摘 要： | 在Gleeble-1500热／力模拟机上采用热分析法和热膨胀法测试内磁屏蔽钢在不同试验工艺参数下的相变点，分析不同试验工艺参数对其影响并建立3种试验工艺下的CCT曲线。试验结果表明：形变促进铁索体转变，使得连续冷却转变曲线左移；同一冷却速率下动态Ar3f比静态Ar3f高，通过降低终轧温度其作用更为明显。

| Abstract: | Transformation points of inter-magnetic shielded steel were measured on Gleeble-1500 thermal/mechanical simulator by methods of thermal analysis and thermal expansion, and three kinds of CCT curves were constructed and the effects of different processing parameters were investigated. The results show that deformation in unrecrystallized austenite region can accelerate ferrite's transfor mation process and the CCT curve was shifted left; the dynamic A_(r3f) were higher than the static A_(r3f) at the same cooling rate, and the clearer effect was testified by lowing finishing temperature. |
