对Q345冷轧钢板两相区退火进行了研究,通过对不同保温时间试验钢板的金相组织以及拉伸试验结果对比,得出如下结论:保温时间对试验钢微观组织和力学性能有影响,790℃下60~120 s退火,可以有效消除冷轧过程中产生的带状组织,并能避免因过长保温造成的组织粗化。

In this study, the cold-rolled Q345 steel specimens were heat treated in different intercritical annealing time and the microstructure and properties were implemented by means of optical microscope and uniaxial tensile test. Through the comparison of the microstructures as well as the tension tests results of steel plates under different holding time, conclusions were drawn that the banded structure eliminated in the holding time of 60-120 s at 790℃and grains had little trend of coursing.
