| 摘 要： | 在热模拟实验机上进行不同变形温度和冷却速度试验，研究低温区变形温度和冷却工艺对CSP生产线上微合金高强度钢的组织和性能的影响。试验结果表明，变形应在单相奥氏体区内完成，适当降低变形温度有利于得到细小均匀的贝氏体组织；冷却速度对贝氏体组织有明显影响，冷却速度越快，贝氏体组织越细小，强度越高。

| Abstract: | Simulation tests under different deformation temperatures and different cooling rates were conducted on thermal simulator. The influence of finish rolling temperature and cooling rate on microstructure and properties of a microalloyed steel produced by CSP line were researched. The test results show that the deformation should be finished in single austenite range and a finer bainite structure can be obtained by lowering the final deformation temperature. In addition, the cooling rate has a significant effect on bainite structure, and the faster cooling rate, the finer bainite structure and the higher strength. |
