| 摘 要： | 利用Gleeble-1500试验机、X射线衍射仪、金相显微镜和透射电镜等手段，研究了卷曲温度对一种超低碳深冲钢显微组织、纳米级析出相和相应冷轧退火板织构的影响，并且获得了最佳的卷曲温度．热轧板中的析出相主要是硫化铜以及硫化铜和硫化锰复合析出物．低温卷曲时，析出相数量少、尺寸较大且分布稀疏．为获得较强的有利织构和良好的冲压性能，实验钢卷取温度应选定在600℃以下．

| Abstract: | The effects of coiling temperature on the microstructure and nano-scaled precipitates of ultra-low carbon steel with deep drawability,together with the corresponding textures of the annealed cold-rolled sheet,were investigated by Gleeble-1500 hot simulator,X-ray diffraction,optical microscopy and transmission electron microscope.It is found that nano-scaled precipitates in the hot-rolled steel sheet are mainly CuS and CuS-MnS.The precipitates are less,coarse,and sparse when the coiling temperature is lower.To obtain a strong favorable texture and a better drawing property,the best coiling temperature should be under 600 ℃. |
