| 摘 要： | 采用H-800透射电子显微镜及正电子湮没技术，观察了CSP工艺热轧低碳带钢轧制过程中位错形貌，并计算了终轧后轧件的位错密度，结果表明：随着轧制过程的进行，累积变形量的增加，位错密度逐渐提高，CSP工艺比传统工艺生产的同规格产品位错密度高约一个数量级。

| Abstract: | The dislocation and morphology dislocation density in the hot strip of low carbon steel after finishing pass produced by CSP were investigated by using H-800 transmission electron microscopy and positron annihilation technology. The experimental results showed that the dislocation density increased with the cumulative reduction increased. The dislocation density after the finishing pass is larger than that of the hot strip produced by the conventional technique. |
